As JR has said 1000 times, its just the Wing T in different clothing.
My HS still runs the same Wing T that they did when I was there in 1994.
What I said was what Malzahn runs is largely based in the Delaware Wing T. What he does is quite different from most of the pass oriented spreads IE Air Raid, but you're seeing his influence in a lot of other teams too.
Which HS?
The Wing T is probably one of the most prevalent HS offenses today. Some are just getting in the gun to run it though, but some are true to the Delaware version too.
At the college level, the Wing T is like the Run and Shoot. Nobody runs either exactly as it was designed, but you see elements of both in almost every offense out there. June Jones is the closest to running the "real" R&S, but even he's added his own touches.
Personally, I'd like to see someone brought in to run the offense that is a Lonesome Polecat Offense guru.
