It's hard to relate to people on Nick Saban's level. One thing I keep going back to is Michael Jordan retiring from basketball to play baseball. That still seems irrational, but the fact is his dad died and he realized it was his last chance to try to become a major leaguer. On one hand it's nuts, on the other it's a rational solution to a problem.
Mal Moore's death had to have triggered some concerns with Nick Saban. Be it over the new AD and President, or just a reminder of his own mortality, it seemed to be enough to make Nick re-evaluate things. It's more rational than it might appear, because there's a ticking clock and Nick probably doesn't want to have any regrets. He's the hottest commodity in the entire coaching world, but in a few short years that will be over.
It's understandable that some people have developed a shut up and coach mentality when it comes to Nick Saban. He's paid millions of dollars and some people can't understand why he can't just take the money and do his job, and leave everyone else alone. In most situations, most environments that surely would be enough. But, Nick Saban isn't most people, and Alabama isn't most environments. He wants everything to be perfect, and he agonizes over things most of us wouldn't think twice about.
I'm not an insider, I'm not privy to private conversations, but there's been concern expressed over complacency and appreciation. This might not seem like much, but those things can be enough to take down any team. If Nick Saban is the head coach for Alabama next year, it's unimaginable that he goes elsewhere after that. The Texas situation developed into a rare chance to make a lateral move, and after that time will eat up what ever chances he might have left. There is likely a rational fear that if he stays at Alabama, there won't be the urgency required to get things done. Some people will settle into the ok, we have Nick Saban, we're good, mentality, while ignoring anything Nick says.
I feel like Nick Saban has been trying to shake things up for a while now, he's been trying to stir up the fans, and arguably trying to stir up the administration. He's said here's what you need to do, and he's gotten some backlash (nothing major, but for a perfectionist it's notable) for it. There has to be concern on his part that he's running out of leverage, once people know he's not leaving, it's easier to just ignore him, and he'll be left dealing with the consequences. This might sound like conjecture, and it is, but if Bill Battle is ok with publicly going out there and contradicting the head coach on TV, what might others in positions of power feel comfortable doing behind closed doors?
I hope Saban is mainly trying to stir things up a little, keep people from being apathetic and exert the proper amount of influence. That might not be it at all, but it feels like that's part of it, and as for the allure of Texas, I'd assume Saban feels like that at least for a couple years, the fans and powers that be would indulge any requests he makes without criticism, which of course makes it easier for him to accomplish his goals. I think Saban has to recognize that in the long run, the move to Texas would be the wrong move (he has to know he can't "rebuild" Texas without damaging Alabama), but right now the Texas situation is giving him the most power he's ever going to have. After that, all he has left is the Barry Sanders approach...
