I guess a couple of posters here seem to forget that PJ began to take Shaq out toward the end of the game so that they couldn't employ hack-a-Shaq. And his freethrow shooting has gone downhill since those days in LA -- he isn't even shooting 50% from the line these days (and hasn't since he was with the Lakers in their last championship run).
All you have to do is utilize your quickness in the post against Shaq -- he will have no choice but to play defense with his hands because he doesn't have the footspeed to stop anyone anymore. Also, it would also be wise to remember that the defensive 3 second rule has been added since those days and that doesn't bode well for Shaq.
