Big12 isn't going anywhere and its becoming one of the strongest conferences. The new playoff rule plays into both the SEC's and Big12's favor. End of discussion.
Kansas is the bottom feeder of the Big12 and Mizzou will be bottom-middle of the pack in the SEC. I can see why Kansas doesn't want to add Mizzou to the schedule, because its already going to be nearly impossible for them to ever be bowl eligible as it is and they don't have the balls that ISU has playing Iowa every year. Oh that's right, we don't suck anymore.
