Having a guy like Niang and Royce for 4 of his 5 seasons certainly helped as well. Minus Niang's freshmen season, when he wasn't as dominant, there's 3 seasons where he had a guy that could get a bucket by himself, no matter the defense, or shot clock situation.
I contend, really good teams are way more about their pieces, than the coaching. Any coach in the country will tell you it's the Jimmy's and Joe's and not X's and O's.
If you add a middle of the road starter, like Hogue, to this team, they have at least 3 more wins. Playing what-if, but imagine this team with Shakur Juiston. Who was very close to committing 3 years ago.
