I'm not sure I agree with the notion that Vols aren't running the ball because opponents are putting 8 in the box. People who watch replays of the Vol games say there are a lot of busted assignments by OL, TEs and Fullbacks. I agree with this. The Vols completed a long pass to open the georgia game, completed another pass, then couldn't run for two yards on second down. You do have to keep safeties honest--and that has been a problem for UT because the blockhead coaches never throw to the TE and because the passing game has not been good. Good offenses make good yardage on first down. UT did that very early--but as the game progressed the Vols were always in bad down and distance situations. The Vols hurt themselves also, IMO, because they are not created and almost never use misdirection. Think about it: The Vols run Riggs and throw to wideouts, so the defense never has to worry about the FB (if he is in the game) or the TE. The offense has a lot of problems--duh--starting with the OC, then the QB position (weak play) and then half-assed blocking by many on the OL, TE and FB.
I see the Vols and other teams incorporating a lot of "sophisticated" NFL type formations--offsetting the fullback, using the H back, audibles at the line, zone blocking, blah, blah blah--but those innovations certainly haven't helped UT move the football or score points. I DO think it is tougher to simply overpower teams with the run these days, as UT used to do--almost everybody has better athletes on defense these days and emphasizes defense. But I'm not sure running the spread or five-wide on most plays is the answer either--especially in the SEC. In a perfect world, the Vols would have an OC who has some NFL experience, is smart and is tough-minded--a Charlie Weiss type. If I were Fulmer, I'd spare no effort to find such a person. But we know the Hand Clapper won't do it!
