Saban is a great coach and a great program builder. Importantly, he knows how to build a program in short order. Even more importantly, he knows how to "manage" the entire program...and make no mistake, you need to have a HC that understands how to manage a program at a place like ND because ND is not just about Xs & Os.
Saban's agent is Jimmy Sexton of Memphis. Mark my words, any job that is open or potentially open and can pay north of where Saban's currrent position pays is going to have Saban in the discussion because Sexton will see to it. Sexton is aggressive and he has made Saban a wealthy man (and himself wealthy) by making sure his name is out there on every search where a pay raise would be possible.
Lastly, I am Catholic as well. I tend to pull for ND when the are down and pull against them when they are good. Saban attended my church regularly while he lived in Baton Rouge. Like me, he and his family typically left immediately following communion. I still remember he and his wife Terry fighting over a recruiting trip as they walked to their car after church one Sunday...really kind of comical.
