I think what this really shows is that bowl games are largely unpredictable. Aside from the playoffs where both teams are fully engaged, trying their hardest. Outside of that, bowl games are a crap shoot.
Second, I think it shows that undefeated, -1, and -2 loss teams in the Group of 5 conferences are NOT comparable to the better teams in the Power 5 conferences. And should rarely be ranked. Far more rarely than they are, these days. It's sort of like thinking an undefeated woman's team should be ranked among the top 25 men teams in basketball or tennis.
But sure, third after those two considerations, it also means the SEC is super tough and awesome. Just squint when you glance at yesterday's Florida-Oklahoma score, or you might reach a different conclusion.
