Well, my Dad is a Bama fan and said he understands. Saban can't even go out to a restaurant and enjoy a meal without some obnoxious shithole running up to him and asking him to autograph the forehead of his new baby. Add in a lot of little reasons:
reputation for never staying anywhere more than 5 years
the unrealistic pressure put on him by faculty, alumni, fans, etc.
news outlets running independent investigations becuase the NCAA turns a blind eye to his program
more...
If he is just trying to suck more money out of Bama, he roped his wife into his scheme by sending her to Texas to look for a house. If that's the case, that's pretty low.
There are three NCAA programs that are "worthy" of Saban and his huge ego: Alabama, Texas and Oregon. And by worthy, I mean, a sufficient (read obscene) amount of alumni and other donor money flowing into the program with no end in sight, facilities that are beyond state of the art, or about to become beyond state of the art,and enough national notoriety to keep the television cameras pointing in your direction. Two of those programs have coaches that are pretty much safe. Oregon and Alabama. The third is remarkably coming back to prominence, thanks to a few timely wins. And IF Baylor beats Oklahoma tonight, and then Texas beats an undefeated Baylor team, well, Mack Brown will have his post for life.
In other words, Saban doesn't want to go anywhere, Texas is putting heat on Mack Brown's ass, and Saban's agent saw the whole thing as an opportunity to get more cash.
