Plot hole: In the Cowboys' last possession of the final game, Spike makes a long run before being stopped on the goal line. The Cowboys' next play is a run up the middle. The Little Giants stop the run and the Cowboys lose possession, but since that was the first possession of a new set of downs, the Cowboys would have three more chances to score.
Plot hole: In the World Series game at the end of the movie, the scoreboard shows that the game is scoreless up until the very end. But Brendan Fraser is portrayed as an amazing phenom who hits home runs every single time he comes up. He obviously failed to hit a home run the first few times up in that game.
