I do think there's a possibility things change, but you don't make a statement that definitive unless you are strongly planning to not go to the Big 12.
Instead you give the other lines "We're confident in Kliavkoff and the conference and are excited for a new media deal" or "We have a long history and tradition with the Pacific Athletic Conference and strongly value that"
So maybe they're planning to join the B1G, but my guess is they're strongly leaning to staying
