It's not an ignorant question. UConn is indeed more valuable than those other schools even to the B12, so the question is more why there is no buzz for UConn to the B12. I think it comes down to two things:
(1) UConn is more valuable to the ACC or B1G than to the B12, and if the realignment situation ever makes it beneficial for the B12 to expand, then it will also make it beneficial for the ACC and B1G to grow, and they'll grab UConn ahead of the B12. On the other hand, if the environment is such that UConn is not attractive to the B1G or ACC, then it won't be attractive to the B12 either (and neither will UCF, Cincy, or BYU), and so the B12 will not expand at all. They will stay at 10, as they are currently doing.
(2) UConn has no incentive to create buzz around the B12 as its landing place will be in the B1G or ACC. Whereas UCF, Cincy, BYU, Memphis, and Boise are in desperate straits -- the B12 is their only possible P5 landing place. So they want to create momentum and a perception that they belong there, as do their fans. So these schools and fanbases are creating buzz about their schools and the B12, but UConn and our fans are not.
