Seeing Pitt in this list tells me you do not understand Big Ten expansion in the least. Pitt is in with Iowa St, Ball St, WSU and OrSU in their chances for BT membership: NO WAY IN HELL. The state already has a member, they aren't a good cultural fit, and they add virtually no new dollars to the conference.
UVA, ND, UNC are the schools the Big Ten has already contacted behind the scenes if the ACC blows up... those are choices 1, 2, and 3 by a mile. Syracuse, Miami, FSU, and Clemson have a chance, but less so than GaTech and probably BC.
