I suspect this "PAC remnants to the Big12" is a stalking horse rumor put out by the remnants themselves, to motivate the ACC to take them. Probably the Oregon St AD that has a track record of misinformation to drive a narrative in their favor.
Makes zero sense. BY isnt taking value detractors now, when there are future ACC remnants in a more populated, better geo-located area that are also good adds to suppurt his bball growth strategy.
Frankly, UConn makes more sense for the Big12 than ANY of the PAC 4 leftovers.
