As Hornets 247 in part put it:

"Aaron Gray’s rookie season was his best at scoring the ball, and he’s declined sharply in his second and third years. (a la Hilton) Sure, he doesn’t fit into the Bulls current guard-oriented offense, but he also has put on more weight on an already "big-boned" frame. In fact, it’s possible that if he sets a pick for Darren Collison, the other team will lose sight of Collison entirely, despite Gray standing sideways in front of him. Though . . . think of the change of direction possibilities! Anyways, he’s slow and not in the best physical shape around."

    …

"The defensive numbers for Aaron Gray over the last two years are abysmal. Due to Gray’s slow feet and propensity to foul, centers averaged a PER of 20 against him, and he most likely was not going up against the cream of the crop while posting those numbers. The Hornets need help defensively as much as they need help on the boards, and he’s not going to do anything to help them out there."
