Okay, this is my interpretation of what has happened in the last week based on the reports that have come out:
1) We heard last week that the PAC is in no hurry to make a deal, and may wait until August or later.
Kliavkoff's strategy this whole time has been to wait. There has never been an offer available that would get the $40 million per school he wanted, and after the B12 sniped the ESPN/FOX deal the offers have been even worse. I think he's okay locking in the schools he has, even if that means they miss the window for SDSU and have to wait a year to expand.
2) Colorado has a private board meeting and schedules a public one which is later canceled. A bunch of articles are written that they are on the verge of leaving for the B12.
Colorado had no intention of realigning this week. I believe the hubbub was all about pressuring Kliavkoff to stop stalling and bring a deal to the table now. Colorado will move to the B12 if the P12 deal is bad, and they see the window for coming next year closing if they don't announce the move by July. I think they got what they wanted before they cancelled the public meeting.
3) Arizona's president goes on a media tour talking about bronze medals and moving if the financials require it. Scheer also throws out there that the ABOR wouldn't block the Arizona schools from splitting up.
I think this was Arizona's setting the table for a B12 move if the P12 deal isn't good enough. There are probably still Arizona faculty and fans that aren't sold on the B12 and they need to get the idea in their heads that this is necessary for the good of the school under the circumstances.
P.S. this didn't happen last week but several weeks ago the ASU athletic director said ASU is staying in the P12. Not sure if they change their tune if UA and CU leave, but for now they seem set in staying even with a bad deal.
