Was it the offense line or Ben style of play: Ben chooses NOT to be a system QB, what I mean is a plant back foot, ball out within 1/2 second afterward. (i.e Brady, Manning, Brees) and for that reason the O-Line looks worst them it ready is: In fact the last two years Ben got hurt holding onto the ball (ie. trying to extent the play).
The reason he does this because he isn't great reading the defense and knowing where to throw the ball, without see the receiver open. Ben dosen't throw the receiver open, as much as he has to see the receiver open.
