Well, if you really look at that old history, you'll find offensive innovations like the wing-T, the Power I, the wishbone. Those offenses differed from basic smash mouth, at least in my mind.
I think that when the Redskins had John Riggins behind the Hogs, that was smash mouth. The Giants, when they had that awesome defense, and a great running game, led my Joe Morris, Otis Anderson, Rodney Hampton. Those are my modern Smash Mouth teams.
Our freeze option in the 80s and 90s were outstanding. When we had a power running back, a quick back who could get to the corner, an RPO QB and some good receivers who could get separation.
It shocks me that Kevin Rogers is as old as he is now, because if there was one guy who I've really liked in my years as an SU fan, it might be Kevin Rogers.
