AU Family recon:
Apparently Auburn also has a legit CB coach, by the name of Zac Etheridge. Etheridge and Doug Belk have worked together in previous stops, and Etheridge is rumored to be interested in following Mason or joining back with Belk on Miami's new staff. This suggests that we beat-out the U for Mason, and the U is now going down the list and targeting Belk.
Evidently this was Mason's digs in Auburn, although he never moved his family out of Nashville:

Auburn has also seen a mass exodus through the Portal. Seems likely that more players could follow Mason to Stillwater now that it's official. No source on that, just my hunch from observing what Auburn is going through.
