Name one. Wilson is a good QB with a good offensive line and uses a good running game to mix up the plays and then when it all breaks down he has the legs of Tarkington to make the play work. Without a good offensive line or a good running game, he would be in real trouble. They surrounded him with the right people.
The Redskins, for one, think that RG3 should be doing it all without an O-line. And Cam's O-line is atrocious.
How many games has Griffin played in the last two seasons? He isn't getting hammered because his offensive line is good, even Cousins can't ward of the defensive alone.
And Cam is hurt again, no offensive line to protect. Cam is a beast, I think people expect him to run down the defense by himself.
