Like I said, he's a capable stopgap who can win games with a decent D. He will be a steller backup and mentor (hopefully for the Bills) when we draft a QB.
Like the OP, I also love this QB. But clutch is hardly a descriptor of him. Roethlisberger is clutch. Even if he's playing a bad game, he will, 80 percent of the time, make the big play in the end to seal the deal.
Fitz, even when he's playing good, will, 80 percent of the time, make a mistake to lose the game.
