One of the benefits of splitting the A-Back out - going to Trip - is it forces one of a small handful of answers from the defense: safety rotates down, linebackers bump over, or they keep two safeties up top (and thus have fewer guys than we do to the trips side).
When they rotate a safety down, you'll usually see us running stuff away from the trips side. Lots of triple option.
When they keep two up top, we'll often run stuff back at the trips side - like that "crazy" or boomerang motion from the wide A-back that you saw.
I had no problem with CPJ's playcalling. Maybe some more rocket toss?
