Other mistake: After the first race, in the scene where Lightning is rushing out on the stage thinking he is the winner, loads of confetti is shot out when the King and Chick Hicks gets onto the stage. The confetti is then falling down, but not a single flake hits any of the cars. However, in the following shots, you can see plenty of it on the stage underneath the cars, even though they haven't moved.
Other mistake: Jim Lampley reacts to a knockdown by saying "That could be the end of the fight right there," then quickly adds "but no!" when he sees that Rocky is getting up. The problem is, we hear the "but no!" just before we see any sign that Rocky is going to get up.
Other mistake: At the beginning of the movie, Brit's parents announce that her father has lost his job, but only a few seconds later he says that the company is relocating to Crenshaw Heights. If he has lost his job, there would be no reason to follow the company to Crenshaw Heights.
Other mistake: When Ricky is pinned to the table and has his arm broken by Jean, he has the bone between his elbow and shoulder broken. However, when they show him trying to saw off the cast with a knife, it ends right above his elbow.
Other mistake: When Haskins and the other coach are going on their recruiting trips in the beginning, we can see the two of them talking on the phone. Funny thing is, that both of them are using pay phones. So who called who? How did they know the number? And how did they know when the other one was going to be near that pay phone? I feel it is highly impossible for one to reach the other when both of them are using pay phones.
Other mistake: In the final game, after Gretchen has struck out for the first time, look carefully and you will see Nelson is running out of the dug-out like he is next to bat. Then in the next scene, suddenly it is Jarrett up to bat instead of Nelson.
