I would have found room for North Dallas Forty, The Running Man, and Horsefeathers. I'd dump Jerry Maguire, Field of Dreams and Major League. I haven't seen a lot of the films on that list, but I don't see any that are better than Raging Bull.
As mentioned above, Jerry Maguire is not really a sports movie, it's yet another Tom Cruise vehicle. Field of Dreams is just sappy and saccharine, for the Iron John crowd, and Major League is a predictible rehash of every worst-to-first movie Hollywood has ever made, with a few memorable moments thrown in. It's pretty much The Natural + The Bad News Bears + A League of Their Own - Intelligence. It loses additional points for having two sequels which are pretty much the same movie, with fewer funny moments.
The Running Man is not that great of a movie, but I give it bonus points for the fact that the sports aspect is central to the plot, rather than used as an allegory for the human condition, like so many boxing movies, in particular.
