The thinking is if Big 12 adds BYU for football only, since their Sunday restriction is nightmare for other sports and they're currently independent in football, then possibly to keep numbers even they'd add a 2nd football only school (or BYU and UConn would be 3/4 added teams). It also solves travel situations for BYU/UConn, only requiring the longer travels for the football programs that can afford it. If we can present ourselves as a solution to the BYU problem, any little bit helps.
Seems counter intuitive based on our football strength, but you never know.
