SI did a study trying to find the best coaches at building elite offenses:

There's a whole lot of info and data here and I haven't read through a lot of it yet, but Fran grades out pretty well. It's broken into "Recruiting for Instant Impact", "Recruiting for the Future", "Talent Retention", "In-Season Development and Optimal Usage" and "Future Development".
He ranked 22nd overall, 8th at in season development and optimal usage and 5th at Talent Retention.
