Each conference may have a somewhat different "style of play" (or not, I think we make too much of it at times). I find it interesting, when say a good defense like UGA had last year plays a Baylor in a bowl game (Baylor of course was not a typical B12 team last season), or Oklahoma. The Sooners scored 31 in the first half as I recall.
I find it all interesting, not really something about which to bicker. I wish the ACC could find some balance, and this year I'd opine Ohio State is almost as far ahead as Clemson. Well, not almost, but fairly far ahead.
Alabama seems to be annually very sturdy, I think they have a mental advantage over opponents in the SEC, at least over UGA.
