I am a little less enthusiastic about Gortat after seeing him play. There were more than a couple of cases where he played what I thought was very lazy defense. His season on-court, off-court stats from 82games are:
Stat ON Court OFF Court Net
Offense: Pts per 100 Poss. 105.2 103.9 +1.3
Defense: Pts per 100 Poss. 109.4 108.9 +0.5
This is a little hard to follow but the bottom line is that the Suns are slightly better defensively when he is OFF the court. Maybe he would snap out of it if he came to the Cs but I saw a guy who was coasting on defense to avoid fouls and then working hard when there was a positive stat involved. He would still likely help but this just reduces what I would be willing to give up for him.
I'm going to have to disagree a bit here. Watching Gortat on Wednesday (and I was actually at the game, not that that means much), it was clear that he altered and bothered a lot of shots at the rim, which gave the Celtics trouble at times. He also killed the Celtics a number of times in the pick and roll, getting easy looks at the rim. The Celtics really need a guy with the ability to rebound, bother and block shots, set good picks, and roll to the rim and finish. Gortat can do all of that quite well.
He's no star, but he's a very solid seven foot center with few drawbacks given his size and position.
