That is true...my bad. I still don't know how a rematch is in ABC's best interests, though.
Not necessarily. Say OU won, and finished 13-0 after clobbering whoever from the old North Division. And UT finishes 11-1, with one close loss to OU in the RRS. The old Big 12 could have had the exact same situation as LSU/Alabama. And they almost did, in the past.
Would we be complaining about rematches in that event? Probably not.
I would be complaining... If you are not the best team in your conference you don't get the right to try and claim best team in the country.
See Nebraska vs Miami...
