Sports Illustrated article says that the B1G Presidents and Chancellors want to add all four - Washington, Oregon, Stanford and Cal. While the media partners only want two - Washington and Oregon.
Maybe another media partner can enter the picture to pay for Stanford and Cal? Maybe they get a lesser deal than Washington and Oregon will get? I get that Stanford and Cal don't move the needle for ratings, but that research money and collaboration is hard to turn down.
A source familiar with the Big Ten thinking said the conference’s presidents are more interested in adding all four schools, while the league’s media partners are more interested in a two-member addition of Oregon and Washington. While one league source cautioned “nothing is there” in terms of an imminent move, a second source said “a real proposal is going to take shape fast” regarding Oregon and Washington.
