The rookie quarterback will start the team's opening game of the 2013 regular season after passing a fitness test yesterday.
The running back told the team's website: "He's a very athletic guy, he can throw it. There's definitely a different dimension when he's back there. All those guys work hard, really.
"Just got make sure he has a calm demeanor and so far he has. I'm definitely excited about going out there and playing with him.
"It's going to be loud and we expect that. We need our fans to be loud, but in order for them to do that, we have to do good on both sides of the ball. In all three phases of the game, we have to keep those guys into it. We saw a couple years ago when we won, how they helped us by being loud."
The Bills play the New England Patriots on Sunday.
