I said something similar in another thread but Simmons is a tragic character. So much talent. You see him move on the court, at his size, seeing the floor, it is stunning how good he is. Then he has to pick up the ball and shoot and his mind locks up. He has had the yips for nearly 3 years. This is all in his head.
But no, the Celtics is not the team that is going to be where he figures this out (if he ever does). It seemed like the Nets might be a good place. He could let Durant and Kyrie take pressure off of him. But after a whole season off and now 40 games into this season, there is no improvement. He is the same.
He is on the books for 2 more seasons after this one, at close to $40M per. In spite of that, I would not be surprised if he is traded again, some other team takes a chance on him. But no way should that team be the Celtics. Even if we had a bad contract like Westbrook or something, I wouldn't want Simmons on the Celtics right now. Certainly not trade an important player like Smart.
