I agree with many Jefferson's faults listed by the OP. However, name one other person on our team who does not get shut down by a single defender. The reason Jefferson gets his number called and people feed him the ball is because no one else seems willing or able to create a high-percentage shot. When Favors' and Kanters' post game is more developed, or when Millsap has reliable moves out on the floor, then trade Jefferson. Jefferson is a ball-stopper and people tend to stand around and watch him, but quite often it's the only alternative to somebody chucking from the wing. Not sure if you've noticed, but our guards/wings are not great shooters.
