Would OKST be the pick if it were objective?
I just can't vouch for a team 107th in total defense. I think the Cowboys avoided a very public ass-beating.
I don't use total defense for anything. It's too pace-specific. I could point out they were top-20 in points allowed per drive. They weren't good in yards per play, though they were about average.
And I'm sure it would did save them an ass-beating, though what happened gave LSU one.
Anyway, there's no exact "objective" to all of it. It depends how things are weighted and considered. I can argue I think having better top end wins and the same record against a better schedule should carry the day. Someone, maybe you, can counter, that style and murdering a lighter schedule, making the case a team is of higher quality but less accomplished, should carry it. (The computers favored OK State after the regular season, but they'd been neutered when it came to MOV/numerical style points)
My main to arguments are this
-I don't think almost any other program would win a tiebreaker with the wins profile they had (the second-best team they beat threw 10 TDs all year, the third-best by record was outscored by 3.2 points a game and outgained by 70). I just don't. We'd be hearing about the low-quality schedule.
-And I think that if Ok State was let in and got housed, all but the most ardent Bama fans would have shrugged it off. They'd lament the missed chance, but in the end they lacked both hardware or resume and lost when they had their opportunity. They'd be like 2008 USC, a team that was hell on wheels but kind of forgotten by history. Bama had a monstrous defense, great tailback, explosive and underused backup tailback and a forgettable passing game. If they get passed over, the end up just one of those teams.
(Of note, Heisman narrative prevented 2008 from being the year that pushed us to a playoff. We had four 1-loss P5 champs, two undefeated G5 teams, two Big 12 teams that lost an unsatisfying tiebreaker and no one was too mad because between CCGs and Bradford vs Tebow)
