Ahh, what does a true sports fan love more than [[BrokenBase doing battle with others]]?

[[folder: Teams/Franchises ]]

* Sports message boards are rife with this kind of strife, even setting aside the classic, easily mockable (Yankees Suck!/Red Sox suck!) back-and-forths between fanbases. Within a fandom there is almost always a BrokenBase. Best-case scenario, fans of a team will simply disagree on the quality of a given transaction. Over a long enough time, however, fans who frequently criticize management are usually accused of disloyalty or outright troll status, while those who frequently defend management are considered irrational fanboys incapable of independent thought. And that's without mentioning the cults of personality that tend to develop around certain players; if the two players should happen to compete for playing time with each other, the {{Flame War}}s can get quite messy. SeriousBusiness, indeed.
* Go ask NHL fans how teams in warm weather cities are doing, and prepare to duck from the flames. On one side are fans who point to Dallas, Los Angeles, San Jose and Anaheim as proof that the sport can succeed in places without snow; on the other are the fans who point to Florida, Atlanta and Phoenix as proof that the sport doesn't work in such areas, with Carolina, Nashville and Tampa used by both sides to prove their point. Don't even try touching the debate about whether the league should be on [[ScrewedByTheNetwork ESPN or NBC Sports Network]] in the US, either...
* UsefulNotes/FormulaOne fanbase is pretty broken. Essentially, there are two types of F1 fans now:
** First, the “purist” F1 fans which highly praise the old times saying it was the pinnacle of the sport and the [[DorkAge 90s was the start of the decay]] [[TheyChangedItNowItSucks with the introduction of driving aids and the refueling]]. The f1 purists also highly praise the classic circuits, like Monza, Monaco and Spa, saying they are the masterpiece of racing while they hate the new circuits for having excessive asphalt run-off areas. While they praise the refueling ban in the recent era, they criticize the restrictions in aerodynamics and engines, saying F1 should pursuit the speed and this will make the races better. F1 purists also often criticize the pursing of safety saying F1 is safe enough now and the drivers know the risks. Purists generally see the new fans and the open minded ones as people which don't know the “true F1” and should watch some classic races before saying anything.
** Second, the “open minded” F1 fans which welcome almost any changes that improve the racing or make the sport more fair, like technology restrictions and the cost cap (which limits the money which an F1 team could spend in a season). They also strongly defend a more fair distribution of F1 money in order to small teams have a chance of closing the gap between they and the best teams, making the races more excitement. Also, the open minded ones don't care about tradition or the historic value of F1. They think it's better to make changes instead of living of traditionalism. Open minded fans generally see the purists as [[NostalgiaFilter nostalgia-driven fans]].
** About Monaco Grand Prix, some fans say the circuit isn't suitable for F1 now, due to the excessive car downforce and the lack of overtaking points, resulting in boring races. The purist fanbase usually hits back saying the Monaco Grand Prix is a traditional F1 circuit and should racing here forever and F1 without Monaco isn't F1.
** The proposal of a canopy broken the base even more (even the f1 drivers have different opinions about this). While the purists says a F1 car must have an open cockpit and putting a canopy will ruin the design of car, making it ugly and looking a Le Mans like car. The other side says F1 must keep improving the safety and the safety is more important than the car design or the tradition.
** About the other open wheel series, F1 purists generally hate Indycar saying it's a luck based racing series and hate Formula E too because of electric engines and the annoying engine sound. Other f1 fans don't mind and some of them follow these two racing series.
* North American open-wheel racing:
** The split (from 1996 to 2008): did you like CART / Champ Car (more road racing and undoubtedly the more popular drivers up until around 2002) or the UsefulNotes/IndyCar Series (strictly ovals until 2005, including the Indy 500, but started adding non-ovals prior to the open-wheel reunion)?
** After the split: The all-or-mostly ovals schedule that was part of the UsefulNotes/IndyCar Series' original plan, or the roughly 50/50 schedule between ovals and road/street courses that's taken effect since 2009? Do you like how similar the cars are, or does it turn you off? Is Danica Patrick a legitimately good racer or is she just eye candy that happened to get a win in 2008?
* The Yankees/Red Sox rivalry: greatest rivalry in sports or the CreatorsPet of baseball due to its massive coverage by ESPN?
* Women's American football
** Lingerie Football League (LFL) vs. "traditional" women's football (WFA, IWFL, WSFL). The LFL proponents point to their organization's success, TV deal (with MTV2), notable arenas, and major publicity, dismissing the fully-equipped women's leagues as groups of elitists who are beneath notice, noting that they don't have one-tenth the publicity that the LFL has. On the other hand, the traditional women's proponents' argument is more one of integrity, claiming they play "real" football closer to the NFL, NCAA, and high school rules, and the LFL is a cheap gimmick, with the women degrading themselves for the publicity.
*** Especially true in markets which are home to both LFL and WFA/IWFL/WSFL teams. It is not uncommon for the traditional women's team to challenge the LFL team to a scrimmage (in Chicago, the WFA's Force to the LFL's Bliss, in Cleveland, the WFA's Fusion to the LFL's Crush, and in St. Louis, the WFA's Slam to the LFL's Saints). Of course, no LFL team has accepted, or even answered said traditional team's challenge as of yet.
* Christian Laettner making the 1992 US Dream Team over Shaquille O'Neal. Today people feel O'Neal should've been the lone college player selected to the team due to being the #1 pick in that year's NBA draft and going on to have a Hall of Fame career. Laettner's defenders point out that while he didn't become a superstar in the NBA, he is still considered one of the greatest college players of all time, won National Player of the Year in 1992 and a national championship, and out-dueled O'Neal when their respective college teams Duke and LSU met in both 1991 and 1992.
* UsefulNotes/NationalFootballLeague:
** San Francisco 49ers fans are a tad divided on the team's move from Candlestick Park in San Francisco to Levi's Stadium in Santa Clara, about 50 miles south. Longtime fans find it a sore point for [[TheyChangedItNowItSucks obvious]] [[NonIndicativeName reasons]], while others point out that the 49ers are headquartered in Santa Clara anyway, so if anything it's a convenience for the players who don't have to travel long distances from their facilities to their home games anymore. Another form of Broken Base concerns traffic; fans in the South Bay are either grateful that 49ers home games are much easier to travel to and also enjoy the many public transit options (several local bus lines, a light rail line, and trains from two transit agencies make stops at or near Levi's Stadium on a daily basis, a benefit Candlestick Park lacked even amongst San Francisco locals), while others (along with non-fans) feel that the resulting traffic practically turns several key expressways and highways into parking lots on game days.
** One proposed idea for Levi's Stadium is for both the 49ers and the Oakland Raiders to share the same stadium. Proponents support it from an economic standpoint (since both teams are in roughly the same region, why not have them in the same stadium, much like the Giants and Jets?), and opponents point out that the Raiders' historically rowdy fanbase (just look up "Raider Nation") and the [[FandomRivalry rivalry]] between 49ers and Raiders fans--known for getting straight up [[SeriousBusiness violent]] at times--make this a very, ''very'' bad idea.

[[folder: Rules of the game ]]

* College football's BCS. Is it really better than what there was before? What teams should be involved in a given year? Do teams from outside the power conferences have a fair chance? And the big one: Should the whole thing just be blown up and replaced with a playoff?
** Now that the BCS will be replaced by a four-team playoff starting in 2014, the argument has shifted to how many teams should be eligible and how can a team be eligible.
* A discussion of NHL fan opinion split that doesn't include the phrase 'shootout'? For shame. It's not just the fans that are divided, opinion of its effect on the game are divided amongst the players!
* Also... fighting in hockey. Many hockey fans love a good tumble but there are many fans who refuse to watch the NHL but love the international juniors because of its clean fight-free play.
* Dispute over different rules codes, or between supporters and opponents of a change in the rules. For example, the "designated hitter" rule in effect in Major League Baseball's American League (but not the National League) has its supporters and detractors. There are also differences in rules between professional and college football, and between professional and college basketball, the relative merits of which are disputed by fans of the sport.
** For the designated hitter rule, its detractors are traditionally from the older school of baseball fans, who believe everyone should have a chance to hit and field, no matter how lousy pitchers typically are at the bat. They believe it reeks of specialization, effectively turning MLB into something akin to modern-day NFL. On the other hand, the DH rule's supporters believe it makes baseball more exciting and high-scoring, while allowing pitchers to focus on what they do best, and allowing certain hitters who can't run or field much due to injuries (or other reasons) to remain productive.
** Speaking of modern-day, specialized NFL and American football in general, many older fans and ex-players long for the days of two-way football, where it wouldn't be uncommon for players to play every single down, all 60 minutes, on both offense and defense. Then again, fans of American football as we now know it believe that playing two-way ended a lot of careers prematurely, and often increased the likelihood of dementia in ex-players.
* In 2005, the NBA changed its collective bargaining rules regarding player eligibility. By the mid-2010s, this affected college basketball's base, breaking it between (more or less) two different ideologies.
** The traditional powerhouses (Duke, Kentucky, etc.) using "one-and-done" players: elite five-star recruits who are students for only one year before declaring for the NBA Draft with an emphasis on individual talent and up-tempo offense. In the eyes of their critics, this was nothing more than taking the student out of student-athlete, practically ignoring defense, and ignoring the team aspect of the sport by trying to turn the NCAA into the NBA-lite.
** More low-tempo, team-oriented, lower-scoring, defense-intensive teams. The chief examples included Arizona, Virginia, and Wisconsin. Virginia's meteoric rise over two years from the barely .500 in the ACC to outright conference champion was particularly criticized by those in the first camp as the epitome of "boring" and "what's wrong with college basketball," and helped spur a shortening of the shot clock down to 30 seconds in 2015. Possibly related to this was that these three teams run the "packline" defense, invented by former Wisconsin coach (and father of Virginia's coach) Dick Bennett.

[[folder: Individual Players/Staff Members ]]

* [=LeBron=] James leaving Cleveland and going to Miami. Was it a betrayal of his homeland and team, or was it warranted, due to his team being ineffective and his free agency period ''allowing'' him to join another team? Was The Decision really ''that'' bad, or was it just a clumsy way to say where he was going to? Can we blame him for The Decision, or does it fall on the shoulders of ESPN for even giving it ''that'' much publicity? Was he flat-out cheating his way into a championship by teaming up with two superstars, or was it warranted, due to being the only competent man in his original team for ''seven straight years''? Many agree that he got cockier afterwards, but does he still deserve the same amount of disdain since then?
* Billy Beane and his "Moneyball" system either does what nobody else thought to do to - make a great baseball team on a shoestring budget, or created an overrated endlessly-copied system which makes for boring play and limited success in the postseason and gives cheap general managers an excuse for not paying people what they're worth. (For the uninitiated, he uses spreadsheets and such to determine from past statistics who the most underrated players are, and he rejects some flashy strategies like stealing in favor of whatever has the highest statistical probability of getting a run.)
* Creator/PeytonManning is either the Jesus Christ of professional American football, or he's an overrated, whiny douchebag who chokes in pressure situations. The latter group had mostly grown silent since the Colts won Super Bowl XLI, but their loss to the Saints was like miracle CPR to them, as Manning threw a critical interception in the fourth quarter of Super Bowl XLIV which ensured a Colts defeat. His stint with the Broncos has done nothing to silence the debate. First he produced an unquestionably great regular season, shattering records and earning MVP in the process only to spectacularly lose in the Super Bowl (though his own statistical production in the game was decent at the very least). Then, two years later, he plays an abysmal injury plagued regular season, gets benched in favor of his backup and somehow still makes it to the Super Bowl which his defense wins for him (though he did not make any major mistake and Cam Newton did not look good in the game either). The debate comes down to individual achievements versus team performance or more crudely "stats vs. rings". Often those debates are complicated by dragging Tom Brady into it who is in many ways Peyton's foil and has his own very vocal fans and detractors.
* Michael Vick, before, during and after his conviction and jail term for dog-fighting: "He's paid his debt. Leave him be" crowd vs. the "That dogkiller should be a pariah" crowd. There's also the third crowd: fans of the Eagles who say "Why did we hire this guy again? [[ComicallyMissingThePoint He can't win a game to save his life!]]"
* Similarly (to an extent), Ben Roethlisberger following the Pittsburgh Steeler quarterback following the recent string of accusations of sexual assualt (particularly a 2010 accusation that led to his being suspended for the first four games of that season).
* Eli Manning (Peyton's younger brother). Genius clutch god who "outbradyed Brady" ''twice''. Or "Fluke to end all Flukes" who got lucky with a ball stuck in a facemask? Not at all helped by the fact that he was the first overall pick in the 2004 draft which produced an impressive amount of good or very good Quarterbacks and went to the team with the most insane media market in the league. As he is still active, the debate will probably only be settled by another Vince Lombardi Trophy or some seriously awful choking. However, the fact that his play outside of the two Super Bowl seasons has been very inconsistent has also played a part.
* Stephon Marbury, he's either a selfish JerkAss who destroyed the Knicks organization, or a guy who was vindictively, blackballed and railroaded because of his testimony at a sexual harassment case that was leveled at the Knicks organization (which damaged their case). Or all of the above..
* Fans of the Houston Rockets have been having a civil war for a long time now over star Tracy [=McGrady=]. His defenders say he's a hard-working player who battled through injuries, was forced to have major surgery, and then after working extremely hard on the rehab has been benched due to their vindictive coach or GM. His attackers view him as a selfish media hound who puts himself before the team, has been faking his injuries for the last 2 years, and is no longer part of the new star-less system created by their brilliant coach and GM that has done wonders for the team. And then we don't even get into the GM, Daryl Morey, who has been bringing the "Moneyball" approach described below into basketball.
* Prepare to run from the chaos that will ensue if you say Alexander Ovechkin is better than Sidney Crosby, or vice-versa.
** This seems to be dying down since it looks like while Alex is good, Sid before his unfortunate concussion was clearly surpassing his famous rival.
** The fact that Crosby has multiple team awards [[note]]World Junior, World Championship and two Olympic Golds, including a 2010 Gold Medal after Crosby and Team Canada beat Ovechkin's Russian squad 7-3 in the Quarterfinals, two Stanley Cups and two head-to-head playoff series victories over Ovechkin's Washington Capitals[[/note]] while Ovechkin and his Washington Capitals have yet to win anything but regular season awards doesn't help Ovechkin supporters, either.
* Kimbo Slice for many mixed-martial art fans. Is he a real fighter, one from the street with no training who just had a bad run, or a hustler who scammed his way onto national television for a buck?
* Tim Tebow for NFL fans. His outspoken religiosity tends to be divisive. His abilities as a quarterback even more. Although he led the Denver Broncos to some amazing comeback victories in the 2011 season, his (in)ability to pass well has sparked much criticism.
** Although his fans and detractors at least seem to agree that the ''Tebowing'' phenomenon is highly amusing, and it has become one of the first major memes of the Internet age that isn't restricted to younger generations, but apparently enjoyed by all age groups in America. (for any Europeans reading this, do a Google image search for Tebowing, you'll see what we mean).
** He continues to be this, despite being the backup quarterback for a team that missed the playoffs last year; during preseason, the New York Daily News was [[http://www.nydailynews.com/sports/football/jets/tim-tebow-watch-day-6-ny-jets-backup-qb-sacked-shut-rex-ryan-press-conference-article-1.1127312 publishing his stats]] ''from practices'', apparently just so people can argue about him.
* The Jerry Sandusky case has done this to Penn State's football fandom, particularly when anything related to Joe Paterno comes up. However, the pro-Paterno faction appears to be the most vocal.
* Jay Bouwmeester brings Calgary Flames boards to rubble at the mention of his name. He was acquired as a player that was expected to take the team over the top, but in a league where 50% of the teams qualify for the playoffs, failed to do that in his tenure. Combined with a low intensity personality and a big paycheck, and the ongoing conflict of him being a capable player on a bad team or being dead weight nearly brought entire forums to their knees.
* Lolo Jones: Fans of track & Field either think she's a media darling because of her great personality, or it's because she's ButNotTooBlack, AmbiguouslyBrown and attractive. Also bring up how the media overly profile her at the expense of her other team mates, whom some believe is more deserving of the attention.
** Compare her to Anna Kournikova (or Kimbo Slice) ForMassiveDamage, which by the way is not a complement.
*** Some would justify her media coverage due to the fact she has personality and is media friendly. But that within itself is controversial. What's more important looks and personality? or skill? Ideally both but her popularity seems to primarily be based on her looks and charisma more so than athletic ability.
* UsefulNotes/AustralianRulesFootball, amongst Essendon fans: Is Kevin Sheedy the greatest coach in the history of the game, or an overrated, self-hyped man who should have won more premierships than he did?
* In the modern boxing world, there's [[TheAce Floyd Mayweather Jr.]] and [[PintSizedPowerhouse Manny Pacquiao.]] Considered by sports experts as the best pure boxer (Mayweather) and the best slugger (Pacquiao) of their generation. Mayweather has spent the majority of his career so far undefeated and on top of the pound-for-pound list as the number one boxer. Pacquiao was honored as the fighter of the decade for his great run that lasted nearly ten years. However, according to the boxing fans, either both fighters are great and represent possibly the last generation of truly talented fighters since both are near retirement, or they're cherry-picking frauds whom carefully chose their opponents to make themselves look good.
* Richie [=McCaw=]: one of the best rugby players of all time and a great leader/role model, or a dirty cheat who gets away with murder by playing the referee? Your answer is likely to be [[FanMyopia heavily influenced by]] whether [=McCaw=] plays for or against your team.

[[folder: Football ]]

* For whatever incomprehensible reason, fans of UsefulNotes/AssociationFootball absolutely adore getting into online flame wars about whether to call it "soccer" or "football".
** And in real life, too.
-->'''John Oliver:''' When you call the sport by that name [soccer], an Englishman dies.
* Arsene Wenger: a manager doing the best he can with limited finances, or a stubborn manager who has focussed on his youth policy to the detriment of the team?
** After the groundbreaking transfer of Mesut Ozil, however, he seems to have broken the image of "stingy old man" for most people.
* Manchester City (and before that, Chelsea): Teams just doing what's necessary to compete with Manchester United by spending bucketloads of cash, or ruining UsefulNotes/AssociationFootball by distorting competition?
* Who is the greater/more iconic English football team: Liverpool or Manchester United?
* The Premier League: The best league in the world that provides thrilling entertainment, or a cash cow that has spoiled the game, concentrated the trophies in too few hands, ruined the English national team by over saturating the highest competition with foreign-born players and that the lower leagues represent "proper" football?
** Although the perception of Premier League is "concentrated the trophies in too few hands" might have been changed due to Leicester City's [[ShockingSwerve shockingly unexpected title in 2015-16]], proving that you don't need to be a powerhouse team[[note]]The season before Leicester won the title, they were ''almost'' relegated, and was actually predicted to be relegated in the season they won it. In addition, Leicester is usually known as a yo-yo team (a team that gets promoted and relegated constantly), and in the 2008-09 season they were in the ''third'' division of English football[[/note]] or need to have lots of money[[note]]Leicester's first-team squad in 2015-16 costs ''just'' 22 million pounds, with normal powerhouse teams has ''at least'' one player that costs more than that[[/note]] to have a shot for the title.
* Barcelona: One of the best sides of all time that provide brilliant entertainment or diving, whining cheats that aren't really that exciting anyway because they just pass it without actually doing anything with it?
* Stoke City under Tony Pulis: Practical, pragmatic tactics that allowed Stoke to stay in the Premier League, get to a cup final and qualify for Europe, or dire, dull and dirty?
* Not only discussions about whoever is the best player in the world today (Messi, Cristiano Ronaldo, Neymar...) get heated, but you can expect the mention of the "greatest of all time" Pelé (or the nearest contestant, Maradona), and discussion on if the player being defended is better than him.

* The animosity between rugby union and rugby league have been going on for over a hundred years, with league supporters accusing rugby union elitist, and union supporters calling league a game for "criminals and northerners." While the vitriol has decreased somewhat since the professionalization of rugby union, the debate shows no signs of going away.
* In Gymnastics, the debate usually is Russia vs. USA. On Tumblr, saying you like the American team better is pretty much a [[InternetBackdraft death sentence]].
* In RugbyUnion, the New Zealand All Blacks' performance of haka before each game. Some fans believe that it's a great spectacle that adds to the contest, while others say it is "barbaric" and gives the All Blacks an unfair psychological advantage. Other teams[[note]]national teams of pacific island nations, the Maori All Blacks and New Zealand's national female rugby team the Black Ferns[[/note]] also do a similar performance before the game, but the All Blacks' one is by far the most controversial, because they are the #1 ranked team in the world and therefore get more attention.
* The rise of advanced stats has caused some vicious Broken Bases over individual players, teams, strategies, and the nature of statistics themselves. As of 2015, the acceptance of advanced stats is near-universal in baseball and basketball (with the exception of some pundits), but American football and particularly ice hockey see spirited debates over attributes like grit, heart, toughness, and winning/choking nature, all of which stat-heads argue are almost entirely made-up.
* The allegations of Spanish conspiracy in the 2015 [=MotoGP=] season has caused some massive Broken Bases over the last few races. The most notable of those though, is the penalty received by Valentino Rossi over his collision with Marc Marquez at Sepang. He was forced to start from last after being deemed kicking Marquez's bike in that incident. Those who sided with Marquez said that Rossi deserved the penalty, since according to them, he rides dirty and he has some notable & controversial incidents[[note]]such as Jerez 2005, for example[[/note]] with other riders throughout his career. Those who sided with Rossi, however, noted that the incident is started by Marquez running into Rossi's knee; had Marquez seemingly let Lorenzo pass him several laps before the incident happened; and there's no way that someone is able to knock down a ''moving'' 157 kg motorcycle with just a kick [[note]]Even lighter bikes (except minibikes, probably) won't fall down from a kick to the body of the bike. As a proof, in a [=Moto3=] race at Assen earlier the same year, Romano Fenati kicked Niklas Ajo's bike (a much harder one compared to what allegedly happened during the Rossi-Marquez incident) and Ajo's bike didn't fell down as a result[[/note]].
* In cycling, any ex-doper returning to the sport, no matter the role, can spark a lot of debate.
