Corrected entry: At the climax of the film where Lucas enters the football game and attempts to catch a pass, he drops the football without ever getting control of it, which should make it an incomplete pass, but both teams treat the situation like it was a fumble and the play continues causing Lucas to get hurt. For it to be a catch, a player has to have complete control of the ball for at least a moment.
Corrected entry: During the locker room scene where one of the trainers is attending to a player's sore muscle, the trainer applys a salve to the player's leg. The player complains loudly that the salve burns badly. Why doesn't the salve burn the trainer's hands?
Corrected entry: When Lucas is marching with his band, he is playing a French horn. Yet, there is no way you could be playing a French horn in a marching band because you need to rest it on your knee while sitting down.
