The implication that how BYU performed on Saturday was an indicator of how they will perform in the future ("If you are satisfied with winning eight or nine games and going to a mid-level bowl game – and I heard from a few Cougar fans after the game that seemed perfectly happy just winning – hey, relish the victory." — No one said they'd be happy with going to a mid-level bowl game. I'm just saying one win where they underperformed isn't reason to panic). Given the well documented injuries on defense, I don't see a reason to believe that. BYU does need to improve at containing mobile QBs, though. One "disappointing win" won't keep BYU from NY6 in an undefeated season.
"if Georgia loses to Alabama or visa versa they're not dropping much at all" — Yes, but if either of them lose to a non-contender, they will drop. Granted, they probably won't, because they are good teams who deserve their ranking (mostly--I felt Alabama should have dropped a bit after barely beating Florida). But there are other teams in the top 10ish who will.
