Im sure he played in most, if not all, but thats not the point. When Battier and Artest are on the floor, Battier guards the shooting guards. When TMAC was on the floor, he guarded the shooting guards. The guys you mentioned that would destroy Artest play the 3 position.
Admit you were wrong, and lets end this silly discussion. Artest is one of the top defenders in the league... still. Which is why you refused to give a list. He is number three behind Battier, and James... in that order. I gave stats where he shut down Manu while Manu was in his prime, and I gave you stats of him keeping Melo, and James below their averages just this past season, and keeping Pierce from going off.
You have thoroughly loss this argument, and we are going to thoroughly whoop that ass if the Spurs make it past the Mavs.
