I did sports movies as the OT Tourney years ago. I know Rocky won. It's not my favorite, but I think it does the best job of not just being a movie about a dude that happens to be an athlete; while also not being a sports movie that doesn't make you care about the people in it.
A movie someone else brought up was Challengers. That movie was so horribly mis-marketed as a sex movie. It had the scene from the trailers, and one other scene. Major League had as many sex scenes. But it was actually a pretty damn good sports movie. I'm guessing because they had Zendaya, the studio made a choice to go a specific way. As a former tennis player, who has torn his ACL twice, I will say the tennis parts of it were spot on. The decision to use the "ball camera" later was cringe, but otherwise, I really enjoyed it
