Straight: The last team the Trope High Wildcats face in the movie is the Vil Lain High Bigg Badds, who break the rules, cheat, and are generally made up of Jerk Jocks and jerkasses.
Exaggerated: Everyone who attends Vil Lain High - teachers, students, even the janitors - are horrible, horrible examples of the worst humanity has to offer.
Downplayed: Most of the students of Vil Lain High are actually not all that bad (and it shows), but they're led by a couple of Jerkasses that occupy the spotlight.
They got their long winning streak by cheating and bribing referees.
Alternatively, we see things from the perspective of the Wildcats, who would naturally view the Bigg Badds in an unfavorable light.
The antagonists of the film are generally more respectable people than the protagonists.
Alternatively, the Bigg Badds are the main characters.
Subverted: It seems like they're evil, but that's just a public image that they've embraced to scare off opponents.
Double Subverted: But they've had the public image so long that many of the current players have bought into it.
Parodied: Vil Lain High's fight song consists entirely of increasingly-brutal descriptions of what they'll do to the other team while the referee is distracted.
Zig Zagged: ???
Averted: Some of the players are jerks, some aren't.
Enforced: "No one's gonna watch this sports movie unless the last team they face are a bunch of jerks!"
Defied: "Just because they're playing against us doesn't mean they're evil or anything."
Discussed: "Sweep the leg, Vil Lain High Bigg Badds, no mercy!"
Deconstructed: The Bigg Badds appear to be jerks, but it soon becomes apparent that they're no worse than the Wildcats, just competitive - and their rivalry has led to both sides being unnecessarily rude to each other.
Reconstructed: The realization leads to members of both teams becoming close friends, eventually leading to a more friendly rivalry.
