That is so sad I feel bad for the guy he had big potential. Chicago has good team and with him they would be dangerous, let's see what will they bring to replace him.
The Chicago Bulls wanted the best for their team and I think they have plan to slowly rebuild their team like the Derrick Rose era or even better than that. Their players hasn't even close to get to the NBA championships for the last seasons. It seems like their current plan not working anymore and to rebuild the team is the only choice.
