He doesn't play because he gets in foul trouble to much. Good offensively, bad defensively.
I have no idea what Pearl's talking about regarding Hall not being a solid rebounder. His rebounding numbers have been pretty impressive the past 2 games with the limited minutes he has played. I think Hall sometimes has a harder time guarding bigger guys in the post due to their size, but rebounding is not his problem. Also, he doesn't take the ball of fast enough with his back facing the basket, although his post moves with his back facing away are very nice.
