1) Look back at Flacco.
2) Drop head.
3) Snap on one-count.
4) Get Flacco killed.

Never looks up again, never holds the ball for an extra second or two to throw off the rushers. Just gives them the best possible jump on the snap.

This O-line might actually look OK on the road if the D-line didn't know the exact instant that the ball will be snapped. It's like a middle-school team. They could even draw some encroachment penalties if they'd just mix it up a little. How difficult could that be?
