No, I know you are probably feeling pretty desperate at this point, but its not time for a Tyreke Evans who is blowing up now under Smart the way it was originally foretold to change his game to fit alongside anybody other than Cousins, and to a lesser degree Thronton. You fit the roleplayers to the stars, not the stars to the roelplayers.
Now this team does need some ballhandling help and could use an extra veteran voice -- the Beno trade isn't looking very good right now. But it has to be somebody who fits into a role around Reke and Cousins and Thornton, because that is all they are going to do. And if you have any doubts at all about that after seeing how Smart is coaching the team...you shouldn't. He knows how to coach stars and is turning them loose in shots, minutes, and focus. Everybody else is going to have to fit in.
