I did the Vegas treatment during March Madness, it is well worth the money if you need to keep a vegas bender going, and it helps mitigate the pain of your bracket being busted on day 2 of the tournament.
Not sure where I read it because it's to off season and there are a million articles, but I saw an article stating that the fins aren't enamored with Tua like everyone else and they are higher on Herbert. I am at work right now and will link the article if I find it.
I agree with you, I think they are just stringing it out so they can announce either Lincoln Riley, Rhule, or Urban Meyer as their next coach soon after the Garret firing is official.
