Stanford and Cal are everything the B1G Presidents would want in new additions. They just aren't what Fox/NBC/CBS want in new additions.
Wildcard: With the additions of Oregon and Washington, the discussion of going to a 10-game conference schedule, and the possibility of adding Stanford or maybe even Cal, the B1G will have more inventory to sell to a 4th media partner. With 4 (or more) west coast teams, that could include a late-night bundle of games as well. Maybe adding Stanford (and possibly Cal) will be tied to what the 4th media partner is willing to pay.
