Plot hole: About half way through the movie, the basketball coach is in his office and you can see a dry-erase board behind him, and a couple of dates such as 3-15-99... however earlier in the movie when they are announcing the basketball game they say that it is the 2000 season. They obviously changed the voice over to 2000 after the release date was changed, however the dates on the board are still referring to the scheduled '99 release.

Continuity: At the slam dunk contest, after O completes his dunk, there is glass all over the court. When the kid comes to get the ball, you can see that all the glass is cleaned up and there again right before O throws the ball. (Time)
