The Power Sweep is an absolute killer play that would bring a smile to Vince Lombardi even today.
You can see the influences of the Wing T blocking.
Obviously if you have an odd front or the defense is shifted to the other side you would have to pull different personnel.
It’s nothing new for coaches to want to limit the running of the QB this play counters the jet and takes advantage of the defense shifting to the Jet side.
Similar blocking can be run with a reverse to the “nasty-slot.”
