Russell is making mediocre WR's look like a bunch of Jerry Rices...
..McCarron is surrounded by NFL talent; all he is asked to do is to manage the game, & throw the ball in the general direction of 5 star athletes. Meanwhile, Russell is forced to inspire average WR's to constantly play above their heads. Russell is, unlike McCarron, constantly forced to make plays for his team. McCarron is QB for a traditional powerhouse; Russell is QB for a traditional 17up. I don't know who is better, but I do know who is being forced to carry the heavier load.
