The ACC has added Miami, VT, BC, Pitt, Cuse, UofL, and ND's non-revenue sports for five FB games a year, primarily to increase their FB revenue generating power. They could have done this a number of ways but chose to go the route of a CCG and to increase the likelihood of more representation in the BCS games by increasing the SOS for their FB champion. This is why FSU and Clemson wanted a FB selection this go around and just as getting to 12 by any means necessary was the goal the last time around. Timing played a huge role in the selections based on who was available and their reputation at the time within the ACC corridors of power.
Miami was always #1. As they needed two more to get to 12. VT should have been #2 but, the ACC was too dumb even then to properly evaluate program values. The VA legislature bailed them out. This is were the timing becomes crucial. They should have chosen between UL and UConn at that point, but neither had established anything on the FB field. They instead chose wo minor legacy programs in Cuse and BC, eventually lucking into the VT and being stuck with BC. In the second round they needed FB by order of FSU and their plus one. They should have again picked UofL and UConn as the best AD's on the east coast still available. But, they picked minor legacy programs Cuse and Pitt. When the last round came by they were left with UofL and UConn and by some miracle created a situation that even the ACC couldn't screw up so long as they didn't give ND a free pass to squat in their guest room (oops). Was UConn the better pick, yes it was. Can't fault them for taking UofL as they are a solid AD that also gets a lot of money from their fanbase. The internal politics by this point made the Uof L pick a certainty. The lore of Jurich stealing the bid is just nonsense. UConn didn't go from in to out because the votes were never there.
The B1G went another route by increasing revenue through large DMA's with public AAU schools with FB programs. The B1G was never going to pick UConn in this last round. Their pecking order was TV, public, AAU. FB never entered the equation. UVa, MD, RU, UNC, GT could all have been picked but RU was always going to be pick #1 because of sheer population.
Which brings us to the B12. The B12 suffers from the same stupidity and internal politics as the ACC does. They are incapable of making the best decision for the group because everyone in out for themselves on every issue. What they should do is work to fashion 5 geographically coherent conferences that all P5's can agree on, much like the NFL did when it expanded. The divisions were mostly geographic but respected the legacy of certain rivalries. Keeping Dallas in the NFC East is the prime example, This of course in impossible so the B12 should look at the next best option. That option would be to improve the league's stability, revenue, recruiting reach and TV reach. The first two are satisfied by simply expanding, and for the B12, 14 is way better than 12. The question should be is 16 better than 14. The numbers for each addition would answer that.
So, now you have BYU, Cincy, Memphis, UCF, USF, Houston, and UConn as potential candidates as stealing another P5 team is as unlikely as a P5 joining the BE in 2002. This is their pool of candidates. If you think 16 is the way to go, then the answer is easy take BYU, Cincy, the two FL schools, UConn, and either Memphis or Houston. Why UCF/USF over either UM or UH? Easy, one game in FL for every team nearly every year for recruiting purposes. Why UH over Memphis? Because it's Texas, no other really good reason.
If the move is to 14 it becomes more complicated. BYU and UConn bring the most $$ and additional TV exposure. Cincy brings the best FB over the last decade and OH/Western PA recruiting and one of the FL schools is certainty. The questions surround UConn's location and lack of recruiting, USF/UCF viability as 4th and 5th FB programs, BYU's independence, distance and religious restrictions, and the size/redundancy of TV markets Memphis and Houston respectively affecting revenue of each add. Since this is about $$ more than anything, then picks are Cincy, UConn, and 2 of BYU and the FL schools.
As it stands, the dummies will pick UCF and Houston and stop at 12.
