Michael Vick and Nick Foles are competing for the role, with Vick having lost the job last season after sustaining a concussion.
The running back told reporters: "That's why they pay [head coach] Chip Kelly the big bucks, to pick the quarterback. Whoever he picks, I'm fine with. As long as I get my carries, I don't care who they pick.
"You get used to everybody, and a guy might go down. Last year, we had so many guys go down. I think if we practised that way last year, we would have been a lot better.
"You're comfortable with the way the guys block, or you're comfortable getting a pass from Nick Foles, or whoever it is."
