I like your thinking Dan! But 2 questions:
1) The above scenario will take weeks/months. How does the BiG get UConn, assuming the ACC grabs them in the coming days? If UConn is truly a target for the BiG, they need to act quickly and can't afford to play chicken.
2) The above scenario puts the BiG at 16(+) teams rather quickly. Based on previous moves, why do you believe that they become the aggressor and are no longer one of the last conferences to react with the SEC/PAC assuming that they can pretty much get whoever they want, whenever want?
