Don't forget 'Slapshot.' I am not a fan of hockey - don't hate it but don't like it either, I grew up in the south and hockey was not big - but that has got to be one of the funniest sports movies of all time.
I rank "Slapshot" up there with "The Longest Yard", "Major League", and "Hoosiers" as the best movie dedicated to a sport of all time. And who could not love the Hanson brothers? ;^)
