All I can say is that when Saban was asked about the Texas rumors a few weeks ago, his answer was "I'm too old to start over again" (insert Saban/honesty statement here). Honestly, I don't think Saban retires at Alabama, and I think there is a decent chance he leaves after this season (particularly if they win the title again), but I think it is for the white whale of the NFL.
I can tell you, if Saban is tiring of the recruiting or the competition, he's doing a really great job hiding the disdain for those areas since he is the one coach pushing a 9-game SEC schedule.
And what did Saban say about the Alabama job when he was still with the Dolphins?
