Fulmer sounds pretty giddy about this year's team. Moreso than last year. I don't think our passing game will be down much thanks to Hancock, O'Neil, and Vinson. I also think that our running game will improve because all of our running backs (with maybe the exception of Coker) have taken big steps this spring. I Think we are better than we think. Not to mention the d-line improvement.
I think you are right. The Vols have one more question to answer. I think the DL will be a big surprise to most people. Mapu was very, very good before leaving. There is no good reason to believe that he won't return to form after having a year to get in shape. The DE's sound very good. The question mark is still depth at DT and whether Williams or Bolden will really step up.
The one remaining question is who will step up at WR. They only really need two guys with the TE's and backs that are available.
FTR, I doubt Fulmer will ever make the mistake of being too optimistic again.
