"...An offer deemed substantial enough would likely convince Big Ten presidents that California, Oregon, Stanford and Washington would be valuable additions to the league from the Pac-12. That figure is believed to be less than $100 million annually.
If the Big Ten makes such a move, it would almost certainly increase the likelihood the Big 12 is able to get some combination of Arizona, Arizona State, Colorado and Utah from the Pac-12, thus crushing the Pac-12 and hanging Oregon State and Washington State out to dry.
"If that [Big Ten move] happens, I think the other [four Pac-12] schools will want to jump to our league," said a Big 12 source familiar with the situation....
Industry chatter has Oregon State and Washington State moving to the Mountain West if the Pac-12 collapses. At that point, the MWC would replace the Pac-12 as the largest FBS conference completely located in the Mountain and Pacific Time Zones.
Adding to the intrigue, the Big Ten and Big 12 share the same media rights consultant, Endeavor, a global sports and entertainment company....
It is believed the Big Ten's current rightsholders, Fox and ESPN, remain opposed to the conference expanding further. It is in the best interests of both networks for there to be a Pac-12, if for no other reason than cost certainty. After losing out on the new Big Ten deal, ESPN aims to acquire games that can be played in the "fourth window" -- after 10 p.m. Fox already has games in that window through its agreement with the Mountain West.
As the Big Ten's primary partner, Fox would likely consider four additional Pac-12 schools "dilutive" to the Big Ten product. Opponents of Big Ten expansion continue to scratch their heads wondering how Cal, Oregon, Stanford and Washington can bring enough value to the conference.
The answer? They don't. At least at first glance. However, Warren's play may be to get in on the ground floor with Amazon during a time in which when streaming is further catching up with linear cable...."
Fox chose not to bid for the Pac going forward. They may consider it dilutive, but they still get better picks than any new bidder.
ESPN obviously would like to get Pac schools cheap, but they don't have much influence over the Big 10.
