A divisionless SEC is likely to have similar exclusivity in their championship game, but they do have the feature of having a higher quantity of schools who have the booster motivation to up-jump and buy some coaching/players for a run at it.
In the SEC though it’s unlikely, it does seem possible that a Mizzou/Arkansas/Ole Miss/Miss State/Kentucky/South Carolina booster group have a nice run.
I just can’t see it in the big 10. I have a hard time believing that the big 10 will be anything other than 5 or 6 schools, then a bunch of schedule fillers.
My pastor told me that all things are possible through Christ, but I don’t think even the Son of Man can get Nebraska a big 10 championship game appearance.
