So what’s your suggestion? It’s easy to yell “BENCH OKORO!!!” It’s much tougher to propose a realistic alternative.
With Sexton out, the other SG options are Cedi, Windler, and Valentine. Cedi is the best alternative. But moving him into the starting role really hurts the bench. Also, Cedi has finally (after several seasons) found a role that he can do well in. I’m not sure taking him out of that role, and moving him back to a role where he’s been much worse, is a good idea.
Windler has been a disappointment obviously. He seems to have lost all confidence. JBB doesn’t trust him at all, and I can’t blame him.
Valentine is … well, he’s the 14th/15th man on the roster.
Until the Cavs can trade for somebody else (a possibility, but not a given; especially not until later this month, after many more players around the league become tradable), Okoro is it.
