When I think of "single threat" QBs who scare absolutely nobody with their running ability, off the top of my head, I think of Jim Kelly, Dan Marino, and Tom Brady.
What Bills fans would not kill to have any one of those 3, in their prime, play on this team for the next 10 years?
I couldn't give a rat's ass about a running ability for a QB.
If he can stand back in the pocket and fire an arm-bazooka like Marino, who cares about running?!
Let the runners run. The passer should pass.
