The preeminent Chris Paul collapse will always be the Josh Smith game:

The one that always comes to mind for me is a game in which the Clips were clinging to a lead and the other team had to foul in the last 30 seconds of the game. Paul anticipated the foul in the backcourt and tried to sell the shooting foul (and three free throws) 75 feet from the basket, only the refs never called the foul and it turned into a horrible turnover on the heave. Too clever by well more than half.
