David Carr is a dumb mobile quarterback who looks good to fans who don't understand football.
He does all the little things wrong, so he is resorted to throwing the dumb check downs all game.
He is fast and mobile, but he holds onto the ball forever. Houstons line looks "cured" right after he leaves, because Schaub is a whole hell of a lot smarter and doesn't hold onto the ball forever like Carr.
People always thought it was the Texans line that was the problem, but Carr was the problem. He is worse than he looks, and he doesn't even look good.
He is a dumb, overrated, mobile quarterback.
