"We should be playing them every single season in an exhibition! "
I 100% agree. Seems like a win-win for everyone involved. SF State gets a D1 game that is in their backyard and Dons get the chance to maybe pull in a few more fans that usual for a D2 exhibition.
Of course, I also believe that Cal/Stanford should be required to have a permanent home-and-home with all three local WCC teams...and SJSU too, I suppose.
