Besides a bazillion wins by all, and good uni's, the only real comparison is that Mack Brown has been on the "hot seat" every year except the season after VY won it....and during Colt McCoy's last 2 years. Seriously, they wanted him gone, gone, gone but vince young saved his ass so he could smile to the on field reporters like he was a crooked president.
As for Saban, he jerked off the Dolphins faithful by backstabbing everything he preaches about today. He is a two-faced control freak that bailed when he couldn't handle the NFL.
