At the championship game between the Warriors and the Porcupines, the lighting is very strong before halftime, indicating that it was somewhere in the middle of the afternoon. However, after the locker room scene, which only takes place over a span of 10-15 minutes in the movie, the sun is completely set, and it is very dark outside.
In the part where Kevin James hands Taylor Lautner the play book, he hands it to him with the rings at the bottom, which is upside down. When the camera comes back he is holding it with the rings to the top, which is correct but Kevin James tells him it's upside down and flips it over, which actually makes it upside down.
