re: Which potential opening week upset would induce the biggest board melt?

Definitely Arkansas over auburn; LSU and Bama would still be in the drivers seat for the SECW. All auburn fans have been extremely dismissive even without having their starting QB, star CB suspended and losing their heisman candidate RB to boot.

This would be combined with the multitude of dormant hog fan accounts that haven't been active since Petrino coming back with a vengeance.
