A report specifying the exact date on which a coaching change is to be announced is not vague, obviously, and either is a fabrication soon to be shown to be such or is based on inside information.
My GUESS would be that some very preliminary discussions took place, perhaps with an agent, and LV folks said they wanted to fish or cut bait by that date else it's off.
I hope he stays obviously, but I would not criticize him for "going home".
LV strikes me as a kind of marginal P5 program with little history that the ACC picked up out of desperation, but they do have some money, though perhaps not so much from pizza any more.
