@Sancho - A.Gibbs is the one who is teaching in this video, why would you say Gibbs uses a completely different system ? Yes Shanahan to this day uses this system, also the Texans use it as well as Kubiak was the OC with Shanahan in Denver when Gibbs was O Line coach.
yea from what i've read and film i've seen on him, he seems to be a very old-fashioned power back who really does best with a fullback to help him chose his lanes/gaps
Adrian Peterson was in this system during his rookie season in Minnesota. I think Eric Bieniemy was his position coach. Peterson was too impatient to master the scheme. But still had an awesome rookie year.
Uh... are you joking? Gibbs used a completely different system from zone blocking. Also, zone blocking is the bread and butter of Mike Shanahan's offense so the redskins are already using this system.
