How good are the hot new coaches

Right now, the hot up-and-comers everyone talks about are Mike Norvell at Memphis, Matt Campbell at Iowa State, and Scott Frost at UCF. For a little perspective, it might be interesting to see whatever happened to the hot new coaches of the past 4 or 5 years. I know Tom Herman, who was hired by Texas, was the hottest last year. I don’t really remember who those coaches were, but if someone has that info at their fingertips, I would love to see it.
