I don't think what the SEC has done really helped them.
It's too early to make a definitive judgement, but in the current model, they're killing it.
But it's hard to say what it will look like in 5 years.
They were killing it with 12. And this year they really played a lot of shitty football, and it will be interesting to see how that plays out. Like you said, too early to make a definitive judgement.
I believe they will always kill it at 14 and especially at 16 because they will have balance in their divisions. This is what Nebraska really provided (and KSU and CU when we and they were good). But their balance is both “traditional” and “newcomers”. And, in a 14 or 16 model (and certainly in a 12 model) there is a greater probability that more teams will have a “good” record, regardless of the % of those teams relative to the conference (i.e. the Big 12 has 90% > .500, I think the SEC has 58%, but that doesn’t matter because they have more artificially created “good” teams). The Big 12 NEEDS FSU and to a certain extent Clemson in some division with KSU, KU, and ISU in order to create that balance and artificially create “good” teams.
You're already seeing backlash over weak-ass schedules you can play in the SEC now, and expansion will only make it worse. No one cares if you have multiple 1-loss teams if none of them play each other.
Chingon has pointed this out a couple of times: what makes the SEC seem strong more than anything is their OOC scheduling: They always have tough conference games early in the season when most other conferences are playing FCS teams. The winners of those games have inflated rankings relative to the rest of the country, and it carries through to conference play.
Uh, I think what makes the SEC seem so strong is that they’ve won the national title like 20 times in a row with 20 different teams. KSU played a 7-5 Miami, Alabama played a 8-4 Michigan. OU played a 12-0 ND team, Florida played a 10-2 FSU, Georgia played a 6-6 GT, Texas played a 6-6 Ole Miss. LSU played a 7-5 Washinton, OSU played a 7-5 Arizona. GMAFB.
The SEC has artificially created league momentum with their league scheduling and it’ hard to see it fading any time soon. Tenn’s down? Well, there’s Georgia and Florida (throw in a side of So Carolina). Auburn’s down? There’s Alabama and LSU (throw in a side of A&M). It’s balanced because those division will not only have Ole Miss, Miss St, Vandy, MU, Kentucky, but also whomever is “down” – Tenn, Auburn, Ark. The combined record of the bottom half of that conference (which is all those teams I just mentioned sans Vandy) is 26-46 (.361). The Big 12’s is 26-31 (.456). 2 of SEC’s bottom 7 >= .500 records, only 1 has a <.500 record in the ENTIRE Big 12.
