I see no reason to be concerned here. He's not going to New Mexico or Iowa, and while yes there is a chance Auburn throws a ton of cash at him, that's a risk we have with basically every prospect out there (and, in any event, they'd be extremely dumb to do that given his family's ties to 'Bama).
Besides, what has changed here to really worry anyone? Yes he's taking an official visit to Auburn, so what? Tons of our signees under Saban have done that. What else? Luginbill mentioned it? Seriously, Luginbill? What in the world does that clown know about anything? In all honesty the guy is probably just trying to drum up ratings for his show on NSD. I would take anything he says with a grain of salt roughly the size of Russia.
I just see nothing to worry about here. He loves 'Bama, we've recruited him hard, his brother is at 'Bama, he considers Saban like a father, we've strengthened our ties to him by hiring Stoutland, etc. Anything could happen, obviously, but I see no reason whatsoever to expect him to end up anywhere other than 'Bama, and if he signs somewhere else it will probably be the biggest recruiting shock in many years.
P.S. Can someone explain to me how some of the same people drinking the Clowney / Crowell Kool-Aid by the gallon are the first ones to soil themselves in fear over Cyrus?
