I hate a running QB who can't connect on passes (Tommy). Might as well just have a RB back there taking snaps.
I'll take a smart pocket passer everyday. One who can get the ball out fast to his receivers and running backs. People think that if you have a Pro style QB you'll get a "statue", it's not the case for every QB. Most of those guys can get the ball out quick to a short route to avoid the sack.
I'd rather not have a guy run around in the backfield, making his OL work for nothing every play, chuck it 40 yards and have incompletions or interceptions.
