Factual error: The movie takes place during a single NFL season. In the beginning of the movie, when Brandon is still in Las Vegas, the paper he is using to pick games shows Seattle playing New Orleans. Later in the movie, still the regular season, Seattle and New Orleans are playing again. They would not play each other twice during the regular season.
Factual error: When Armand Assante's character confronts Brandon on his bike, it is right near the end of the NFL season, which means it is late December or early January. The trees in New York City would not be green like they are.
