I hadn't given serious thought of Kansas to the Pac Ten, but it makes ever more sense if A & M wanted to go to the SEC, which rumors indicate they are. You have four contiguous states, Colorado, Kansas, Oklahoma and Texas with six teams from the old Big 12 that form the P10 East along with the Arizona schools. I think Kansas has become more attractive after this past week.
Jim Delaney strongly stated no more Big Ten expansion for a minimum of 12 months. I believe we have already seen that the Big East is being proactive. They will do something after this coming Tuesday depending on the outcome of events. If one or more of your arrangements occur, the Big East is certainly going to go after Kansas (should they not go to P10) and Missouri and possibly Kansas State and Iowa State. The only reason I say possibly is that I do not think the Big Ten wants more than one Big East school and may not take any. Getting Missouri and Kansas would greatly enhance the Big East for football and still keep the BBall league at 18 rather than 20.
For the Big Ten there are ACC Universities that offer a lot of benefits over the Big East schools mention under expansion. Much will depend on Notre Dame. I think ND is waiting to see what transpires with the Pac Ten, SEC, Big East, ACC and the seeming demise of the Big 12. Delaney putting the brakes on will allow Notre Dame to get the picture and the impact of remaining independent.
