Only way I see that happening is if Saban knows the NCAA is hot on his tail about something. It's been a few years, Bama is overdue for another round of probation.
Rumor was probably started on TheBunker (crazy auburn fans message board). Same place all other negative rumors about Bama get started, i.e. - ttown menswear, gadsden chargers
I've heard rumblings that Saban's agent is tired of fighting all of the folks at Alabama. Most of it is about years and raises for his assistant coaches and support staff. All of his assistant coaches are very under paid in the SEC. Rumor has it that he will leave the Tide before they renew his contract again.
I've heard that if Les Miles ever leaves LSU that Saban would want to go back there, or possibly to Texas if that spot were to open up. Who knows?
