In their infinite wisdom, the scheduling Gods of the Pac-12 have scheduled the Big Game (that's Cal-Stanford for those of you unfamiliar with the moniker) for October 20 in 2012. Which means that the rivalry game for those two teams will be played in mid-season, rather than the traditional Saturday before Thanksgiving spot on the schedule.
This is a travesty...and having attended 13 Big Games in my lifetime, I can tell you that it just won't be the same. From what I've read, both schools have pledged to work with the Pac-12 to ensure that future Big Games are put back in their rightful spot on the schedule. One can only hope that they're successful.
