I'm biased , but I think his physical presence is so big just moving about in the lane, it must be like trying to dodge a moving cement mixer and not get run over if your the other team.

He is so tall, he doesn't have to jump at all, just be big and tuff, and hold postion and he will get garbage rebounds and a few points. He is now wide as he is tall...
It is PAINFULLY obvious when the O Neals are in the game , we pull ahead or hold ground .
When BIG BABY comes in , he gets trounced inside by the other taller players. He can go to floor for loose balls and hustle, but we need ABOVE THE RIM D too. Thats why Green has to stay in the game when KG is out
Few minutes of Baby against 500 + teams is good for Celtics.
