He graduated 92% of his Black players this year, and they are required to go to class.
Given, they're probably taking many a powderpuff class, but they still do attend.
Also, a University of Alabama degree isn't frowned upon. It's a respected institution, and produces many excellent graduates who go on to become quite productive in society.
Regarding who replaces Nick Saban... Currently, most places are speculating that it's either Dabo Swinney, Mike Norvell, Steve Sarkisian, or Dan Lanning, with all of them except for Norvell being under Saban at one time or another. Lane Kiffin was also mentioned here and there.
At this point, Alabama can take its time and choose wisely. There's an obscene amount of talent on the roster, and even the second stringers could be starters for almost any other Power 5 program. Even if the new guy isn't quite as good as the greatest of all time (Saban), he'll have plenty to work with like Ryan Day did at tOSU.
