Top 10 List: Totally agree on Carl Weathers as #1. He was made for that role, but it didn't define him as an actor. He's had a long, successful career in all sorts of roles.
Jimmy Chitwood should be higher, if only for the scene where Coach is talking to him at home and he's swishing almost every shot, and there were a few of them. You know Gene Hackman wasn't going to stand there grabbing an almost flat ball for several takes, so he must've practiced like a fiend to prepare. "I'll make it" - one of my favorite scenes in any sports movie.
Also, Kevin Costner was such as smooth athlete. I guess he played baseball when he was a kid or you would've listed those movies as well. Tin Cup is on my short list for something I'll stop and watch any time I find it while surfing channels.
My only disagreement is with Charlie Sheen in Major League. There were others in that same movie who looked more natural than him.
However, great effort here. Keep 'em coming!
