33% of the time the underdog team won the CCG and every time the top team was ranked #1 or #2 in the nation. So the BIG 12 potentially lost out on 5 more BCS (or Bowl Alliance) championships because of the Big 12 championship game. Ironic how things played out for them last year.
The SEC has only had it happen 5 times out of 23 CCGs In two of those the winner was going anyway and in one neither team was going to the NC. So basically 2 times in 23 games for the SEC.
