Yeah, I get all that. That part's easy.
Woody runs a "1 gap" 3-4. Looked to me from the Alcorn game that we usually presented an even front, meaning we generally had one of the OLBs (I don't know Woody's terms here, I presume one is the Sam, Groh called the other one Jack I think) on the line rushing, for four total rushers (an even number). I didn't pay too much attention to our coverages, but I'd like someone to break those down for me. Cover 1, Cover 2, Cover 3 (hopefully it's not C3, that defense is garbage) Man under/over, all that crap. I don't understand that stuff very well, and I don't understand run fits at the LB level as well as I would like, as they relate to gap control.
My intuition about the Groh years, which were 2 gap defenses, is that the LBs got their heads lost in gap control sometimes instead of in ball hawking. But I think everybody had their heads lost under Groh.
