Movies about an Average Person's Decision and Hard Work to Become Exceptional in a Sport

I come to this board, hat in hand, looking for help.

I need a list of movies that tell the story of an average person's decision and path to becoming exceptional in an athletic endeavor.

I can only come up with two examples right now.

First, Vision Quest is about a good wrestler who "decided that he needs to do something truly meaningful in his life. He embarks on a mission or, in a Native American term, a vision quest. His goal is to drop two weight classes to challenge the area's toughest opponent, Brian Shute, a menacing three-time state champion from nearby rival Hoover High School, who has never been defeated in his high school career." (Yeah, that's a quote from Wikipedia.)

Second, Breaking Away tells the story of an average young man who becomes obsessed with cycling and decides to becomes an exceptional cyclist. (I highly recommend this move.)

I'm not particularly interested in movies: (1) about a team, (2) about individuals who are already incredibly talented, or (3) about individuals who have to overcome difficult circumstances to be an exceptional athlete.

Please help. Please give me movies that fit my criteria.
