Tend to agree. I think the pool of potential B1G candidates has shrunk considerably. Texas, Notre Dame, UNC, and UVA. I think that B1G ADs would consider two more schools if paired up with a "grand prize" candidate: Oklahoma with Texas; Florida State with UNC. OU has very poor academic metrics though and that would be a stretch consideration for B1G Presidents to swallow. FSU is in better shape academically than OU and would give B1G ADs the football recruiting ground to salivate over, but they wouldn't be continuous if paired with UNC.
At the end of the day, I think the B1G will just stick to the 4: Texas, ND, UNC and UVA. But probably not until this new FOX deal expires.
