I think KS wanted to come back to UGA, then Saban guilt-ed him into staying at Alabama. I think Saban reminded KS that he gave him the job as DC at Alabama when KS was relatively inexperienced, hired him at Miami, etc.
From KS's perspective (after Saban's “sound” advice): he could stay at Alabama under Saban, run Saban's defense, which is already in place, and grow his potential for a head coaching job. On the other hand, he could go to UGA, use what he's learned under Saban, install it from scratch at UGA, and risk not succeeding.
From Saban's perspective, he didn't want someone he's taught his defense to go to another SEC power and use everything he taught him against him. He was going to do everything he could to keep KS.
KS doesn't really have that much experience as a DC. I'll admit there's a little bit of “sour grapes” to that thought, but on reflection I wish we'd offered Chavis or Foster $700k instead of Smart. Both have 15+ years experience as DC's....
Bottom line for me, the most important thing has already happened: CMR FINALLY fired CWM. I'm confident CMR will hire an outstanding DC.
BTW, be kind. My first post!
