No, the rule is to have Notre Dame if at all possible. Given their recent record, they have to settle for the best available midwest team.
Of course, Ohio State is the only northern team to have won a BCS championship. (4 SEC wins, 2 (former) Southwest Conference wins, 2 (current) ACC wins, 1 PAC 10, and Ohio State)
Or, to put it another way, Confederates 8, Yankees 2.
As a girl originally from North Carolina, can’t say I’m unhappy about that!
