This same dude Tweeted something about Pitino/Alabama earlier this year. As far as I can tell he's just a fan and shouldn't be taken any more seriously than that guy in Arizona who Tweeted that Shaka had agreed to a deal with Minnesota a couple years ago. Actually, the Shaka guy actually had some basketball credentials, but a similar situation.
Money aside, it's not a better job, and leaving after two years without doing much will make him look like a tool. But anything's possible.
Plus, I'm not sure how big of a downgrade it would be if he went and Teague re-united with Grant.
