USC and UCLA have told the Pac-12 and the rest of the world they will leave and join the Big Ten in 2024. It’s a major decision, with incredible ramifications the sport over.

And it won’t happen for two years. That’s an awful lot of time to stay living together with the ex you just dumped. In the interim, USC will try to win a Pac-12 title or two on the football field and UCLA will look to get the crown back on the basketball court while the other 10 members frantically figure out their next steps. Of course, it’s not USC athletic director Mike Bohn or UCLA AD Martin Jarmond’s job to look out for Oregon State’s interests, but acting on their own figures to make for an awkward working relationship over the next two years.

That will reportedly crystalize this upcoming week when the league descends on Los Angeles for Pac-12 Media Day. According to longtime Pac-12 insider John Canzano, there have been some conversations about excluding Bohn and Jarmond from the closed-door meetings that will take place between the league’s ADs.

From Canzano’s reporting:

There are some bad feelings circulating. The conference feels jilted and blindsided by the move. UCLA and USC are bracing for what promises to be an awkward football Media Day next Friday in Los Angeles. And there are some developments that suggest that the sides won’t be chummy over the next 23 months.

…

Head coaches Chip Kelly (UCLA) and Lincoln Riley (USC) will be at football media day along with players from their respective programs. But a source at USC told me on Thursday that the Pac-12 reached out to the Trojans this week to discuss whether AD Mike Bohn should be allowed to participate in athletic-director meetings that are part of the schedule. UCLA was also contacted about Jarmond’s presence. I suspect neither will end up involved in those closed sessions.

…

It may get ugly at points. I imagine the Bruins and Trojans will be greeted with hostility from opposing fans when they play conference road games this season. That comes with the territory. And I don’t find it unreasonable for the Pac-12 to draw some boundaries and shut the defectors out of strategy sessions. But what’s evident is that the sides are unlikely to be glued back together — even by a pile of money.

The first sign things weren’t going to be, to use Canzano’s phrase, chummy came several weeks ago when the Pac-12 replaced Jarmond with Arizona AD Dave Heeke as the conference’s representative on the NCAA D1 men’s basketball selection committee. Jarmond was appointed to a five-year term last year.

We’ll have on-scene coverage from Media Day on Friday, July 29, which promises to be awkward and entertaining.
