Saban is an ego maniac. He could never live with himself knowing that people would suggest that Malzhan ran him out of Alabama. And I personally believe he never intended to sign with Texas, and only allowed it to go this long to keep his name and his University in the headlines after a crushing defeat by it's rival.
Auburn and Florida State are playing in the national championship in a month, but in the last week before the dead period in recruiting, what was on ESPN all day, every day? A bunch of people arguing about how great of a coach he is and how much money Texas was willing to spend for his greatness. And for a solid hour on ESPN, there is a breaking news banner running once every minute about Nick Saban.
