I realize you wanted hoops to reply to this, and I'm not him. So I'll keep this short and sweet.
At UVa Lazor did a great job. The talent was mediocre in some places and horrible in others. He put them in positions to succeed. His best work was with the pocket passers. His OL was the strength. He used his RB in a variety of ways to get them space to run, and he threw to his TE's and RB's enough to take some pressure off his WR's, who were subpar. The QB thing was because none of the QB's really were particularly good except Rocco. The head coach didn't want Rocco to be the QB, because another QB was a big re-recruit and the coach wanted to establish inroads with other recruits with that coach and in that area. So, the head coach repeatedly gave that formerly highly rated QB prospect another shot. All it succeeded in doing was to break Rocco's rythem and undermine him with the team. Rocco eventually got fed up ... but not at Lazor. Lazor brought out the best in Rocco, and put Rocco in positions to succeed. The bottom line was that the head coach squeezed Rocco out with his constant insistence on giving his prize re-recruit a 2nd, 3rd, 4th, ... 84th chance. It was farcical.
Let Lazor play Rocco all the time and that offense hugely overachieves. But, that wasn't Lazor's call. In Miami, Lazor will be working with a faaaaaar more talented QB in Tannehill who has the accuracy, intelligence and work ethic to take advantage of Lazor. We will be improved.
