Other mistake: In one flashback to a Carter-fight, while Carter is resting someone rubs his back with a sponge to cool him off. The sponge is dry when it should have been wet.
Other mistake: The Tigers are the visiting team, so should be at bat first.
Other mistake: Multiple mistakes are made at the end of the game against the Wildcats. Before the final touchdown, the Wildcats are shown leading 13-0 with 6:00 minutes left in the game. After the touchdown, the Wildcats are shown leading 20-3 with 3 seconds left in the game. Based on Mox's position in the two shots, no other plays happened, meaning that the time and score in one of the shots is incorrect. The clock also continues to run when the touchdown is scored even though it's supposed to stop.
