Levine's issue was not getting his stud QB in on time. Briles had Kolb, Sumlin had Keenum, Herman benefited from having a guy like Ward who proved to be worthy of being a winning QB in college. Had Levine gone with Ward to begin with over O'Korn, Levine might still be the HC. That 13-1 2015 season was just waiting to happen. Levine just didn't get the chance to capitalize on it, Herman did.
