Audio problem: Al's piano playing does not match his finger movements.
Audio problem: When Knox shouts "You blind as a horse's ass" later on in the movie, his lip movements don't match with what he's saying.
Continuity mistake: In one of the first games the movie shows, announcer Ranch Wilder has a bruise near his eye. This bruise disappears the following day, and is never heard of again at any point in the rest of the film.
Suggested correction: The bruise did not disappear the following day. It is noticeable on him while he's in the press box at a following game. It's at 20:38 into the movie. You can then see it from 20:38 up until 20:46.
George Knox: You're Roger's mom?
Maggie Nelson: Nope.
George Knox: Aunt? Grandma?
Maggie Nelson: No, we're not related. This is a short-term foster care facility, I run it. Roger is a ward of the state.
George Knox: I see. So Roger, he's got a wild imagination? Always coming up with stories?
Maggie Nelson: No actually, he's very grounded. Truth is most kids who are taken away from their parents by the court system, have a good handle on reality.
Trivia: At the end of the movie, Carney Lansford spits out chewing tobacco. In reality, they used black liquorice to obtain the same look without having to use the real thing.
