He's completely cooked. Someone might squeeze a little out of him in tiny spurts, because he has size, good passing ability and experience, but that's about it.
In 626 minutes of playing time this year, he has zero dunks, can't defend, and is a below-average 3PT shooter. Can't really rebound anymore, either.
Maybe his skill level translates to the bench for a little longer, but nothing to worry about missing out on.
