Probably a long shot they would pick UB, but shouldn't the Big12 be looking to expand by 2 given they only have 10 teams? They've already expanded East with WVU, could pluck UB and another eastern-ish team that plays both football and basketball at a high level like say Cincinnati. It's probably more likely they would pick a regional team like Houston and maybe UCF makes the jump to a power 5 conference.
