For wrestling the Pac-12 will still have WSU, Oregon State, CSUB, Cal Poly, and UALR - for now. ASU will have a new home in the Big12, but maybe Stanford will re-affiliate for wrestling? There was talk of the non-revenue sports staying out West to save on travel but I don't recall if it was Stanford/ACC.
Cal Bap, AFA, NoCo, UVU would be a nice geographical fit if they wanted to reaffiliate with the "new" Pac. Saves the Big12 schools a little bit on treks out to and from the likes of CA, WV, ND.
