No and No.
I still maintain that despite our problems in the South Carolina game, we still would have walked away with a win if the refs hadn't given the game to South Carolina. That non fumble call was as bad as the phantom block in the back with Alabama. Lots of truly terrible calls, but that fumble not being called gave South Carolina 7 points, if that hadn't happened we'd have won by four, even with our defense going to crap.
But Auburn was ranked South Carolina wasn't. Always better to beat a ranked team.
I'd rather have Mizzou at home then Vandy, why? Because playing at Vandy is pretty close to a home game anyways.
