I agree, SEC isn't at the top anymore. You can't suffer those embarrassing losses and still be considered the best. The team's they played were good, but losing by double digits is another thing. If OSU beats ND and Minn beats UNC, I think a case can be made for the B1G. You have elite teams at the top with some nice depth in this instance with Minnesota and Iowa as potentially ranked teams. There are a ton of ACC/B1G games this week. Not a bunch of marquee teams outside Minn and UNC playing, but let's say IU beats UL, while not a great win, it does make the OSU win over IU look better. If one conference does really well this weekend, say a 5-1 weekend, I think that conference will separate as the #2 conference this far. And I expect the ACC to beats the SEC in rivalry week outside of GT beating UGA. So I do think this weekend is important as far as conference pecking order.
As far as a conference getting two teams in, it really hinges on ND IMO. If OSU and USC win, I think there is a good possibility of the B1G and/or P12 getting two teams. But that depends on other teams. If FSU and Texas play like they did against LSU and Bama I can't see them losing. UGA is looking like 13-0, so there might only be one spot available. It will be interesting. If those there go undefeated, what will shake out in the B1G and P12. Honestly, if there are 5 undefeated P5 champs(I know very unlikely) UGA, based on potential resume, SHOULD be the one left out, but we know that's not happening.
