While you have made some solid points in this thread, and generally do in most posts, the "perfect" angle is a little much. Nothing and no one on this earth is perfect; while perfection is indeed a goal it is hardly attainable. I expect our VOLS to compete and give their level best on every play, in every game...which is not to say be "perfect". This year, and last year as well, I expect them to be in a position to win every game. I do not think that is having a "2nd tier frame of mind".
Now, if perfect is to address the final record - even teams that manage to go undefeated cannot be anointed as having "perfect execution" through the course of a season. It is interesting to look at modern era coaches / teams for perfection. Among active coaches, Pettersen and Meyer (2 different schools) are the only 2 who managed to coach perfect teams more than once. Even the mighty Saban has only managed 1 "perfect" season. Nebraska, Auburn and OSU are the only schools w/ more than 1 "perfect season in the past 20ish years.
If it relates to conference wins, well that is attained by various teams throughout each season - but most lose OOC or bowls to wreck a "perfect" season.
Finally, if it is soley related to being "The" Champion...well, there are plenty of "imperfect" teams that have met the metric.
