Yes and no. AD and Bam are two of the most switchable and versatile defenders in the NBA.
But I still firmly believe that Gobert is incredibly overrated as a defender. He is absolutely a guy who really only blocks shots.
I'm not necessarily saying that any of those guys
don't deserve to be on the All-Defense team. There are a lot of ways to analyze defensive production and lots of guys who deserve to be there are going to be left out since there's only 10 spots. But for the rebounding leader to get 3 votes out of 123, the steals leader to get 2 votes out of 123, and not one guard to make the first team tells me that there's a pretty large perception gap here between guys who have the reputation of being a stopper and guys who are actually contributing to defensive stops. That's the part I take issue with.
REBOUNDS -- Most of the guys being recognized in the DPOY voting and the All-Defense voting are great at forcing tough shots and misses but someone still has to grab the rebound or it's not a stop right? This is the most fundamental measure of defensive production.
STEALS -- Every team should have a defender in the paint who can erase layups and force guards into taking awkward angles in the paint that lead to missed shots but a consistent point of attack defender disrupting the ballhandler, icing the shot clock, disrupting plays before they get started, and forcing TOs that lead to easy offense is equally important and equally worthy of recognition.
If all you have is a shotblocker the other team is just going to shoot over you all game. Guarding the perimeter has only become more important in recent years so shouldn't we be recognizing elite defensive guards more now rather than less?
I can understand why the move was made to make the All-NBA and All-Defense teams positionless as the talent distribution in the league isn't necessarily going to be even but in this case (with the All-Defense teams in particular) I think it's only contributing toward a continued misreading of how team defense works. Based on these voting results someone might conclude that a team with 4 Centers on the floor is going to win every game. Of course we know that's not true. Guards are just as important and the point is that the skillsets of your guards, wings, and centers need to compliment each other.
