I think is Okoro is actually a very good defender on the right people. Put him on a 6'2"-6'5" guy who is not a Curry/Young level sniper/ball handler and he's very good. It's not that he has no place, the problem is his place of effectiveness is limited. His best position is like a relief pitcher - when the right matchup is there, bring him in for the innings necessary. But don't expect him to throw a complete game.I guess it is semi-competent defense, but over and over we see guy truly destroying like Russell last night and he cools them off.
