Fake checks doesn't really solve what I'm describing. The point is we would not see the real look until about the 8-10 second mark because they are counting on us taking the time to do the (fake) checking.
As for blitzing, if I'm a LB and I'm trying to time my blitz against this offense, what better way then just wait until the 5 second mark to start showing it? You don't even have to be looking at the play clock to hit 5, just look up and see it is at 10 or 15 and count to yourself.
Really I just think we need to have 1-2 plays a series where we snap the ball quickly and keep everyone honest. Maybe we do, but I can't think of us doing that other than on QB sneaks or goal line plays.
