I completely understand your position. As an anthropologist, I recognize a revitalization movement or "messianic cult" when I see one, and Grudenmania has all of the earmarks of a classic example. If the prophecies come to pass, however, then we are dealing with the realm of facts.
I share your cautious optimism. There are a very limited number of people who truly have insider information. Until Dave Hart says, "The next head football coach at the University of Tennessee is _____," we will have to exercise patience and hope that our fervent prayers to the football "gods" are answered to our satisfaction.
