Seriously though I think there's more than 1 right answer here. Also this diagram drives me crazy because the QB doesn't have enough depth and that backside square in should be more of a climb or drag.
@slattimer we still pulling backside guard on bootlegs, I kind of like the whole OL selling out on zone step to the left there and washing everybody down.
With a full roll a lot of coaches would say what I call a squirrel route as 1, backside drag 2, backside post 3.
If the QB did a half roll instead of what appears to be a full roll, I'd say that backside post is #1, front side corner #2, backside drag #3, squirrel #4 aka outlet
Will a full roll some would do the opposite of the first option: corner #1, drag #2 squirrel #3.
As a defensive coach, I'm just hoping that back doesn't run a wheel out of the backside and my corner is out there chasing backside post
