Because you have to have 12 team in your conference to hold a conference championship game. That is the reason Colorado and Utah join the PAC 10 next year so they can conference championship game. Go Bears!
yes there is a minimum number of teams to have a conference championship game. i might be wrong, but i believe it is 10. the big ten will no longer have a conference chapionship game.
In 1988 when Big 12 Conference teams Kansas and Oklahoma met. Kansas won, 83-79.
Kentucky beat Syracuse 76-67 in the 1996 NCAA Men's Basketball Championship game.
Connecticut beat Louisville, 76-54, in the Women's 2009 NCAA Basketball Championship game.
So we know who the best is....it is the toughest conference.
I would guess all of them since to make it to the Super Bowl a team has to win its conference championship game.
