As I was watching the game I notice the QB's squat really low to the ground when under center. It seems like there head is barely above the centers. It also seemed that this caused the QB's, pretty much all of them, to be about a 1/2 second slow as the hand to stand up and back pedal at the same time. All of the QB's lined up this way, including Hirshman who really had to squat down to get that low. As I don't know all the little neuances of QB I was looking for someone to tell me why they do this. To me it seemed to throw the timing a little off on some of the plays. The slow start for backpedaling was most noticeable on the screen passes where it seemed the the D would have beaten the hell out of the QB's on several plays if they were allowed to.
