It still makes zero sense to me for Saban to leave Alabama and go to Texas. What would be the point? At best, that is a lateral move. Yes Texas would offer him a ton of money but I'm sure Alabama would do it's best to match it. At least enough to where Nick wouldn't want the headache of relocating and starting all over at the collegiate level.
It would make MUCH more sense to me for Saban to leave Alabama to go back to the NFL because success at that level is still something he has yet to accomplish. If Saban moves to Texas, it's either to coach the Cowboys or the Texans.
