Factual error: At the time the film was made, the Celtics team sucked, always finishing low in their division but for movie purposes they are a good team because they made it to the NBA finals. When Mike and Jimmy are talking to Larry Bird they comment on the Celtics real-life situation that they used to be good but are not any more. Then Bird replies saying he hates fans like that who support the team when they are winning and don't support them when they are losing. Obviously forgetting about the movie plot where the Celtics are actually supposed to be a good team that wins most of their matches, get to the NBA Finals and only losing in 7 games to the team with the best player in the league.

Visible crew/equipment: In various shots during the basketball scenes the camera zooms in on the cardboard cutout people that were used to make the Boston Garden appear more crowded.

Continuity: When Lewis Scott is told to get into the finals game he is shown unzipping his jacket twice.

Continuity: In the Scene where Lewis Scott beats up Jimmy & Mike on the outdoor basketball court to escape from them it's pitch black out one moment then seconds later it's completly light out.

Continuity: When Daniel Stern orders the drinks at the bar after seeing the Celtics lose game 6, he makes an action asking for two extra things in Lewis Scott's drink. The two bartenders place all three drinks on the table in front of them. Then Larry Bird shows up, after talking to Bird, Daniel Stern shouts "Where's our drinks?", but the drinks were already placed out in front of them.
