I see your point, but in the situation of a botched snap, you still have some time to react. I have paid attention to quite a few botched snaps, and usually, the holder either has time to either scramble for yardage or roll out and hope for someone to get open. Nobody expects a botched snap so the defense is caught off guard. BTW, correct me if I'm wrong, but wasn't Crayton our third QB at one point in the season last year after Henson was cut? I'm sure Crayton has seen some plays behind center in practice during that time.
