Name some good offensive post players other then the ones I've selected?

The only reason you can't think of any others is that you've restricted yourself to centers and power forwards. Baron Davis is a terrific post player, and he's bigger than most point guards. You've also limited yourself to the offensive end. Marcus Camby is the game's best interior post defender, and next to Dikembe Motumbo, in my opinion the best ever. The up and coming "post" stars are Emeka Okafor and Tyson Chandler. Both guys have unlimited talent.
