Jack O'Callahan DID in fact win a College National Championship
The movie portrays Jack O'Callahan at being really angry for not
winning a college National Championship because of what happened with
McClanahan in 1976.
Fact is, that Jack O'Callahan did win a National Championship in 1978
with Boston U, where he was also the tournament MVP.
But the movie made it look like he never won a college championship, so
that's why he's all angry at the beginning of the movie.
