In his position, he knows a lot more about football and this conference than you ever will. You do know he talked to Brett Yormark last week.
The only people that know anything are the administration at the target schools and the schools who have contracted the conference office about expansion. Unless Gundy is talking to the presidents of Pac 12 and Mountain West schools or sitting in on executive sessions of regents meetings, he doesn't know crap.
You've been all over the place in this thread, but if you go back to June 2022, July 2021, October 2016, and basically all of 2010-11, these moves have been leak free and coaches, including Gundy in the past, have expressed they weren't in the know.
If something happens in season, Gundy might find out after you. If it's out of season, he might find out a few hours before you do.
