This excerpt is everything I've been saying for a long time. Truth is that Grey is more useful to this team than either of Amir or Ed specifically. Gray may be less talented, but his sheer size makes some plays look so effortless while both Amir and Ed's lack of size make those same plays look arduous. I don't think it really matters which one you keep, but one of those two should be packaged.
Also, Barbosa is staying and We should look to trade DD and one of those bigs for a better young player that might be looking for a change of scenery.
