I think Steph, Andre, Donovan, Thabeet and Nadav are locks. Ironic that in a Hurley era focused on offense, we get at least three of our all-time best defenders. I don't think recency bias is even a factor with those three.
Steph is already being viewed as a "lockdown cornerback" in the NBA, and Andre was simply a game changer who had to be on the floor simply because he was a defensive savant.
As for Donovan, he became a tremendous shot blocker who made penetration nearly impossible. How many times did we laugh at teams that kept trying to take the ball to rim?
Thabeet was an incredible shot blocker, and Nadav was like Andre in that he had a unique defensive skill set. No pass was safe when he was on the floor. Although we had other good defenders, Nadav was really our first defensive star.
