The B12 isn't a position where the they need to grab schools the ACC might want as backfill post-GOR.
The only thing that matters is per-school media money. Since these talks stalled, I have to assume UConn wasn't going to help the B12 out in that regard. Post-GOR, the ACC leftovers need to keep pace with the B12 or they'll very likely lose additional members to the B12. If UConn doesn't help the B12 increase their media money, how would they help the ACC?
A lot of people were floating SDSU, UNLV, Boise St and maybe some others as B12 targets to outmaneuver the PAC. Turns out that would have been completely unnecessary. Even if Houston and BYU were available, I don't think they would have moved the needle enough to land them a media deal on par with the B12 and ACC. The PAC could've have the numbers necessary, but not the dollars. The ACC likely ends up the same place, however they'll probably have enough schools left over to backfill and continue on as a relatively distant #4.
