Blue sky time.
ESPN will have to spend somewhere. And that spending could be adding PAC and in cashing out the positon on the ACC.
2-3 PAC in the SEC isn't too different than 2-3 in BIG. And if it were a 4 team independent pod aligned with SEC-ACC super conference, it is no real change for ND, other than USC is now BIG.
Is there a functional difference with UW, Stanford, Oregon, Cal, and ND all being independents in football, but with ESPN? Or that Pac4 being some pseudo conference in football? Add Utah if needed. The total costs won't be more than an entire conference, and if it got you ND, worth it. This isn't the era of GT, or even the 90's in which you needed a conference for inventory and rights negations imo. ESPN League has more than enough. Give them and ND an invite to the SEC football tournament
