Shumpert on the Block?

Once again, trade rumors are swirling around Knicks guard Iman Shumpert.   Shumpert is the Knicks only ascendant young player and one of the best defenders in the league.  What's more he's the best defender on a team that can be pretty lax on D.  His offense has also grown and he shows signs of turning into more than just a transition scorer.    Not only can he play D and steal the ball, he's  good rebounder for a guard, and last night added 9 assists.    So why do they want to trade him?  Seems personal, and that is no way to run a basketball team.  If they do move him, it better be for a very good player and a first in the 2014 NBA draft.
