could be huge on those longer passes they did last time. IMO I think that Forbes was looking too much at the QB which made getting by him that much easier. At the same time I think that having Q back there will provide a better deep cover aspect plus he'll keep the back end more aware as well.
Add to all this is the fact that Young had the game of his career for the most part, not that he can't play like that again, but really what's the odds of that? Thew odds are heavier for Matthew to have a game over him.
It's true Q hasn't played in a while, so rust could factor, but to offset that he has the freshest legs in that back field.
