Lot been written the last couple of days of how Dirk favours dribbling left and uses the hand to defend so it's going to affect him, maybe not in shooting but there's more to the game than just shooting.
No matter what else happens, Dirk HAS to rebound better. The days of him getting by grabbing 7, 8 boards isn't good enough, particularly with their 3 guard line-up. In this situation, the great forwards (Bird, Duncan etc) would go out and grab 15+ boards in this game so that has to be his goal. Control the boards, they're in with a better shot.
