There are four key blocks in the Volunteers' signature running play. The first is the hit that the fullback lays on the play-side outside linebacker. The second is the block that the play-side guard makes to seal off one defensive tackle. The third is the block the play-side tackle puts on the middle linebacker. The fourth, and perhaps most critical, requires the other guard to pull and hammer the play-side defensive end. "If we get every defender accounted for," says Volunteers coach Phillip Fulmer, "then our tailback [ Travis Henry, above] is one-on-one with the free safety. That's a situation we like."
