History is the best indicator of future actions

Does anyone have any detailed knowledge relative the chronology of Saban to Alabama? We all know about the multiple media denials, but does anyone have any information about when Bama first made contact , how long the discussions lasted and what closed the deal? Did intial contact occur prior to Shula being released? Was it with Sexton or another third party? I think a lot of this may provide insite into what , if anything, is going on here.
