With the unbalanced schedules in the SEC, I think the committee will be a lot less hesitant about SEC-SEC super matchups. It will almost be inevitable, with how stacked the league is, but will probably see more heavy handed movement in the committee rankings to ensure the inevitable SEC-SEC super pairings are not rematches.
Nothing definitive, but I think Nebraska-OU and Tech-aggy are going to be very likely to happen as super pairings. I think the committee will try to avoid sending Canady to pick up losses #4 and #5 to Texas. They know the best chance for Canady to make OKC is to keep Tech out of Austin.
Texas could end up seeing someone like Duke or UCLA if we don't end up with an SEC team who gets to host as #14-16, like maybe Arkansas. Because regionally, and regular season matchups, we'll have played Tech twice, OKST, Arizona, Mizzou, OU and LSU.
Baylor is in a weird situation for the postseason - they will have already played the 3 biggest schools the committee could send them to (aggy, OU x2, Texas) in the regular season. They also play potentially geographic destination regional opponents Nebraska, Mizzou and Arkansas in Palm Springs. They're going to end up in Baton Rouge or something, I'm sure, or shipped out west to UCLA.
