Revealing mistake: There is a flipped shot of the Sharks' sidelines, showing all of the jersey numbers inverted.
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: At one scene at Yankee Stadium when the crowd is panned, someone in the background is wearing a Jeter # 2 jersey. The #2 is reversed, showing the shot was flipped.
