It's arguably the biggest game of the week. There's only been 2 times ever that they haven't attended a FOX broadcast game, but both times were last season with the Colorado/Colorado St game on ESPN the USC/Notre Dame game on NBC.
They also almost always go to whichever location has the Noon ET kick on FOX, so even if they don't pick the Oregon/tOSU game there's a solid chance they won't end up here anyways.
