Leon tells the story of him and Stanley playing Gonzaga and John Stockton but he never played Temple in reality. Gonzaga and Temple have only played once in 1999, a year after Stockton lost to Jordan in The NBA Finals.
When Stan tells the story about the car accident that injured his hand, he said he threw out his hand to keep Leon from going through the windshield. Since Stan was driving, he would have injured his RIGHT hand, not his left as is shown throughout.
At the end of the film Boa is wearing #22 for the Boston Celtics. Number 22 was retired in 1963 for Ed Macauley.
