Sims decommitted?
They didn't need him. 7 deep at 4-star athlete position.
Or it could be that Saban saw ESPN has him as a 3-star and decided to "encourage" him to look elsewhere.
Seriously, he probably decided he wants to try to be a QB in college, which is what some expected him to do, and realized he would never see the field as a QB at Alabama. And if he thought he could be a QB at Alabama, the 11 pass attempts probably wasn't very encouraging.
