Sac State's bid for the Pac 12 Thread I get all that and agree with you about the importance of the rivalry, but I'm not sure how these schools are expected to work together, and to what end. I honestly want to know in what ways you think Sac and Davis should be working together.
The rivalry is hard to embrace and promote when Sac is jumping divisions and leaving the conference we share. All the other teams you mentioned are conference / subdivision mates. Sac and Davis will be neither.
As I stated above........
Sac has created two issues:
1. Does it make sense for Davis to play a rivalry game on the road every year? No
2. Does it make sense for Davis to play the same FBS team every year? No
