... for the Big XII and Big East to be the major losers.  

The Big 10 would pick off MO and NE from the Big XII, along with Rutgers from the Big East.  There would be probably be political pressure to accept Pitt and ISU.  If ND decides to join, then the 16th team would likely be either Pitt or ISU.  

Meanwhile the PAC 10 would take CO and Utah.  To fill out to 16 there would be a struggle with the SEC over the plums TX and OU.  Of course, to get TX and OU, politics would likely require the conference to take TA&M and OkSt.  Both the SEC and PAC 10 would have room for all four.  In this struggle my money is on the SEC.
