I think you mis-characterize Saban and consequently any comparison between Saban and Elliott.
First, you should have said that Saban did what Elliott would LIKE TO DO...because Elliott hasn't done anything yet, other than turn down an opportunity.
But second and most importantly, Saban is totally unlike Elliott because he has self-confidence. He had self-confidence when he coached at Michigan State. He had self-confidence when he coached at LSU. He even had self-confidence while he was with Miami. And he had self-confidence when he took the Bama job. The same kind of self-confidence Tony Elliott seems to sorely lack.
Saban went to Bama because (a) he wasn't having as much fun in the NFL as he thought he would, (b) Bama was throwing lots of $$ at him, and (c) they promised him, by all accounts a control freak, an unusual level of control over all aspects of the program.
None of that sounds much like Tony Elliott, to me. I don't think it's a very useful comparison.
