So, lack of perimeter defense against Houston, Phoenix, Miami, Golden State, San Antonio, Dirk's fault. Gotcha. Avery Johnson getting outcoached by Pat Riley and Greg Popovich, Dirk's fault. Gotcha.
Tim Duncan doesn't guard Dirk because he abuses him on the high post. Yao Ming doesn't guard Dirk because he abuses him on the high post. Amare Stoudemire doesn't guard Dirk because he can't guard an empty gym, much less a top-five player in the league. There are very few two-way franchise players. Dirk isn't the only star player to get hidden on defense.
Wait, I thought depth charts didn't matter. In any event, Dirk causes just as many mismatches on the offensive end of the floor for other teams. He's a decent help defender and a lousy on the ball defender. He's much less of a liability on defense than his buddy in the desert. And having Dampier out with a torn rotator cuff really hurt us against Golden State because nobody was back to protect the rim from dribble penetration. Don Nelson put Baron Davis and four wings on the floor against Dallas, who was Dirk supposed to guard. We don't get any offense out of our center position because Diop and Dampier are needed for those post players like Duncan, Yao and Amare in order to get out of the West. It means we're vulnerable to smallball teams like Golden State. That's only partially Dirk's fault, not ALL on him.
