Not to mention it adds the element of the quarterback run game, so it forces guys to stay disciplined in their assignments,” Diaz said.
This speaks to the point many of us are trying to stress when commenting about the QB's running ability and how it impacts the RPO.
It's not about the QB doing a designed run from that play-call. It's about the defense having to honor the POSSIBILITY of a called QB run, and staying disciplined in their lanes.
When they stay disciplined, it has the ability to allow for more creases to occur in the inside run game if that conflict defended doesn't come down hard.
It's my opinion that Kaaya not offering us that run threat is why Walton had difficulty against the better defenses. Defenses played us single high, and defended us well with their talent. Or, worse, they played us 2-high and their DL destroyed our OL without fear of the QB ever sneaking out the back door.
