Mate, Southern still has a-backs. Wesley Kennedy is one of the best i've ever seen. They just call them slots.
They option off a shotgun pistol set when they option. They actually just run a ton of zone. They dont line up two rbs off tackle and motion em. They actually put a hb on one side, or what we would call a te and run zone. Its really not even close to what we did. They even have two te sets. Their backs are almost always in the deep backfield.
Owens isnt coaching them anyway so its a moot point. But their rbs in pistol of shotgun based wishbone do different things since they are not slamming a dive every play they have way less responsibility to arc the lb. its just different.
And it will help lamar remove the military option stigma for sure. And thats my main point. Its a good career change. Ga south runs the ball in scheme more similar to when clemson and auburn run it than cpj; some similar sets and blocking. They just run it more....
feel free to watch a sample; they simply don't line anyone up that can be called ABacks. Just a traditional TE Hback.
