Personally, I would rather not. Cal is capable of being a decent coach when he is motivated, and he hated us even when he was still our coach. If there is one game he will be motivated to actually show up for, it would be against us. More important than that, I just would prefer to avoid the shitshow that would come along with it. The game won't even be the focus if we play them.
That said, my feelings reverse if it is the championship game we meet them in. At that point any game is a circus so whatever. There are far better teams we could have to play in the SEC championship game, and Cal's butthole will be clenched so tight he won't be able to think straight.
