Remember that big post about the MWC and its BCS bid I wrote up yesterday. Boy, am I glad I spent the time on that one.
Utah officially accepted its Pac-10 bid and will join the conference in 2011 according to this PDF from the university. That means the MWC has zero chance of taking advantage of the timing technicality in trying to get its automatic bid.
It still lists Colorado as joining the conference in 2012, a year after Utah, Boise State, and Nebraska settle into their new homes. I guess that makes the Buffs the Boston College of this round of realignment.
