Yes?
The PAC, Big 12, and ACC will never again have deals that come anywhere close to the Big Ten or SEC.
So long as the Big Ten is not extending invitations to any additional PAC schools -- which they absolutely are not, they would've done it at the same time as USCLA -- then there's nothing to talk about with PAC schools leaving.
I don't think the Big Ten looks at expansion again, until/if:
- Notre Dame is on the table, and/or
- ACC schools get freed of their GoR and are interested in moving
Then, at that time, and also highly depending on what the SEC wants to do ... then, we could see additional movement.
There are precious few "needle movers" left for the super power 2. Notre Dame is an obvious one. And there are some ACC schools that would be juicy for the Big Ten, for all the right reasons (market, institutional fit, etc.).
