Have you watched Pavlovic play? He is absolutely horrible... especially on defense. LH is WAY better than Sasha just for the defense alone, and it is not as if Pavlovic is a great scorer. He is a liability when he is on the floor. That is the reason they had to get Murray midway through the season. Pavlovic was getting eaten alive.
Hughes is a better defensive player then Murray and Pavlovic no doubt. And all 3 suck azz at shooting. But having watched the Cavs Hughes is hardly an improvement over Murray, I thought Pavlovic did okay on defense and offense but maybe I didn't watch enough cavs games.
