Oh I agree the Big Ten needs a championship game. They have it in basketball. The Big Ten, of course, has teams that don't play each other, and rotate every two years who they don't play. I was at MSU when we didn't play OSU for two years. Kind of a let down, really.
And in the history of the SEC Championship, there have only been a few rematches. The game seems to always be between two teams that didn't play each other.
