I haven't seen Hoosiers in ages, can't remember much of it. But I'm always up for a Gene Hackman movie, so will have to put it on my viewing list.The "snow" game was insane.
The Bulls minor league team was there for decades before the movie. I think the movie just uses them as a backdrop. I saw the movie once, but like you don't really care for the movie. Just googled it and apparently the team was founded in the early 1900's.
On the other hand, of older sports movies, I do still enjoy Hoosiers. The basketball movie about an Indiana high school coach and team.
Have you seen Big Fan with Patton Oswalt? It's kinda bittersweet, but I like it. There's also The Fan (1996) with Wesley Snipes and Robert De Niro, for the life of me I can't remember whether I've seen it. Despite poor reviews I might give it a try, though.
