Yes -- he is still in the league -- with the Nuggets. His role is purely to help the young guys. He doesn't play at all. But he accepts it completely and is good with it. So he is making $2.3M to spend a year doing this.
Perkins has no game left. (he didn't in his last stint with Cavs) But good for him for trying.
Rumor is that the last open Cavs slot was for him. Holland and Perrantes are 2-way contracts, so the Cavs have two slots open towards 15. Not sure why though, what they really need is a rim protector.
