Hurry-up DL rotation

[sonnyjim]

It is often said that the purpose of the no-huddle offense is to hinder defensive substitution. It changes the recovery rhythm. When Cincy went no huddle last week the Falcons stopped the DL rotation and got a little gassed.

I bellieve that with defensive helmet communication BVG could tell Lofton to designate two linemen for substitution pre-snap. The substitutes would be sent down to the line of scrimmage pre-snap. At the whistle the designated resters would immediately head for the sideline and pass the subs on their way in.

What am I missing here?
