***To show the blocking scheme, I used an endzone view. The back will check then feather release to the side line. The number one receiver will be the other screener in 2x2, while in 3x1 the slot opposite the back will be the other screener.
Because it is a double screen, we used a mirror count system....ie the tackle would have the overhang player, guards would have inside linebackers and the center would pick up the most dangerous player, usually a safety or we would get a double team on an inside backer. This way the line play is consistent in a 2x2 set as well as a 3x1 set.
We use these progressions for most screens (Bubble has a different progression for us, as we block that more like playaction) for ease of learning and to maximize the reps.
A couple of examples:
Playaction game next....
