Just watched half the game on my lunch break.
Sullinger, looks solid did a good job muscling Aldrich out of the paint. Dennis Scott commented that aldrich couldn't get position on him. He was 0-2 from 3, one was a shot clock running out chuck the other just a poor shot. All in all looks decent.
Melo, Big and was moving well
JJJ, does look a bit heavier and very active. Still just needs more lower body strength to be an effective 4.
