I'm scared to extend Mitch with his injuries, I would like to sell high on him.  But Mikal still has one of the most valuable skillsets in the league.  I don't mind extending him.  
But if FO thinks Mitch can stay relatively healthy, he is an absolute game changer in a playoff series.  He's sort of the only guy in the whole league who can do what he does, the way he does it, in the playoffs.
