Tate was not only a great defender, but could come off the bench and spell at the 1, 2, or 3. Even watched him at the 4 on one occasion when the team went to a small-ball pressure lineup.
As for Vlad down low, I think of Darryl Monroe who came in as the softest 280 lb guy you'll ever see. When he left though, still had that soft touch and great passing, but could also back guys up and tear down rebounds. He wasn't quite Jai Lewis, but he made 250 lb Tony Durant his b!tch when they played. We'll never know if Vlad could have had a similar turnaround - not a banger, but an inside/outside threat similar to a Kevin Love.
