Revealing mistake: In the game where Moxon has the 40-yard Scramble (against the Broncos) Tweeder seems to teleport around the field. He starts out on the far side (waving his hands), then has a block on the far side (as witnessed by the close yard marker), the scene cuts and he's on the near side of the field blocking (Moxon runs behind him), then he's on the far side (as Moxon gets up from diving Tweeder is behind him). Some fancy editing going on there.
Revealing mistake: When Darcy and Lance are "having sex" on the drier and the overweight Billy Bob enters you can see that Paul Walker still has his underwear on (it actually looks a lot like a cup) but this would imply that they are faking the sexual noises.
