AJ Green.

You used Randy Moss as an example in the OP. Even Randy Moss looked lousy with lousy QB's. Then he went to NE and he was breaking records left, right, and center. Would the same happen with A.J. Green having Tom Brady throwing to him? You can still force them the ball and get them some yards, but the point is elite receivers are never going to look as good as they could or should with questionable-armed, mentally weak, one-read QB's who are only accurate if they have a perfect pocket, a wide open receiver, are loaded at every single skill position, etc., and all goes according to plan. 

See also: Tebow Demaryius Thomas vs. Peyton Manning Demaryius Thomas. I don't think Thomas suddenly decided to become elite; I think Peyton legitimately singlehandedly added like 600 yards and a handful of TD's to his stat line and helped make him look elite.
