I'm guessing that if ISU and KU do make it in the B1G somehow, thay are going to have to bend over and take it for a long while in the revenue sharing department. That's fine, whatever it takes. Same is true, although to a lesser extent, with the PAC12.
You might be right, which is part of the reason ISU & KU to the B1G makes sense: The B1G can get compelling, Power 5 brands in ISU and KU (at least in basketball) at a "bargain price". However, given the disparity between the B1G and Big 12 in per school revenue, ISU & KU's initial share may not be far off their Big 12 allotment. Plus, the stability, brand and negotiating power of the B1G will position both schools well for long term growth.
