Factual error: In the final game of the movie, when LT gets hurt making the big stop, the referee's measure for the first down before anybody attends to LT.  LT is nowhere to be seen when the measurement is made yet he was supposedly knocked out at the point of contact - where the ball should be. No way would they measure until the injured player is taken off the field and the pile up cleared.

Continuity: Of the people in the stands, almost every other one is a piece of cardboard with a picture on it and a balloon in their hand.

Continuity: Towards the end of the movie when the long touchdown is made and then flag is thrown you see Jamie Fox running up to the referee with his helmet off, when they show the scene from a different angle his helmet is on.

Continuity: At the beginning of the movie, the score on the scoreboard and the score that is shown on the screen are different. This happens throughout the film.

Continuity: In the final Game (at Texas Stadium in Irving) there are several low angle shots that show the hole in the stadium roof.  Throughout the course of the game, the shots show a night sky, then a day sky and back to a night sky, all within the same game.

Continuity: In the final game in Dallas the middle of the field is painted red. Foxx runs for a long gain at which point he does a spin move where you can see he is 30 yards past the red part. When he is hit he lands on it.

Factual error: During the final game against the Knights, whenever the score is shown on "TV", the Knights' score (home team) is shown on top and the Sharks' score (visiting team) is shown on the bottom. In sports, the visiting team's score is always on top and the home team's score is always on the bottom.
