Chicago Bears Linebaker Lance Briggs is a huge fan of comic books, especially of The Darkness, X-Men, Pitt, and Silver Surfer. A big enough fan that comic books are more or less all he talks about, though he tries to be discreet about his hobby. When asked which super hero he would be he just sighed, rolled his eyes and said: "Well, I wouldn't wear tights. I would have leadership qualities. I would love to be a mind reader. That would be my power. But no tights. A snug fit, but no tights. What color costume? You want to hear me say orange and blue. No, something dark. I would be strong, dark, macho. A medium build. I would wear a loose jacket, a contemporary costume. I am not a tights guy, man. You get caught in tights, and you cannot get out." The sign of a true comic book geek.

Former Boston Red Sox pitcher Curt Schilling plays war games and MMORPGs. Originally, Schilling planned to start an MMORPG company after his retirement from baseball; he wound up starting Green Monster Games (now 38 Studios, who developed Kingdoms of Amalur) before he retired. Once, when Schilling used to pitch for Arizona, he was rocked for two homers in the same game by former teammate Doug Glanville. After the game Doug dedicated that beating to the memory of Bing-bong, his Everquest character that Schilling had left to die. Schilling has such a good relationship with Sony Online Entertainment that he asked them to add his likeness into EverQuest II for a charity event. The developers agreed, and put his voice, face, and likeness into the game, complete with his jersey's number painted on his red armor. This very character would later become a permanent part of the game under the name of "Clint Gilcrush". He also founded the company Multi-Man Publishing specifically to keep his wargame of choice, Advanced Squad Leader, in print following Hasbro's purchase of Avalon Hill. The man is dedicated.

Dick Barnett, who now has a Ph.D. from Fordham University.
Phil Jackson, future Greatest Coach of All Time, who was a peace activist, would-be philosopher, and an avid reader.
And probably the nerdiest of the bunch, Jerry Lucas, an eccentric who had a photographic memory, was well-known for his love of magic tricks, and even created his own language, which he shared with Bill Bradley (the pair used it to fluster and frustrate defenders on the court, and by all accounts it did its job well).

He has worn this nickname on his jersey throughout his entire career.

Wojciech Szczesny, the starting Goalkeeper for Arsenal and the Polish National Team, could be compared to Wil Wheaton in his nerdiness, except he plays professional football instead of being an actor.
