The proximity of Louisville to Cincy can be viewed as a positive or negative.
Cincy's airport is in Ky and they bill themselves the gateway to the South. In many respects it's a southern city. Similarly Southern Ind,and Ill,are much different than the northern part of those states.
It gives the Cards their traditional rival going back to Metro days.
But with Cincy not in a P5, Louisville might look at it as a opportunity to expand.
at their expense. The BC strategy. Louisville support drops off outside the city limits as UK owns the state. So capturing some of Southern Ohio is a possible strategy.
Even in the city itself UK fans make up a good % of the population. Cincy has the same problem in Ohio. with the OSU.
Iowa State brings nothing to the B1G, their more of an ACC team ,number two in their state. (Except VA and Carolina maybe BC ) see Clemson,FSU,Louisville,Duke,Wake,NCS,Pitt. VPI,Miami
The B1G wants only flagships
Kansas at least brings a new Market
