Lane had been a college head coach for all of a year when he set foot on the USC campus, and they had just been hit with NCAA sanctions, too. And he went 8-5 his first year and 10-2 his second, despite that. The end of it was a 7-6 season and a being 3-2(!) the next one. They fired him a couple games after the sanctions expired (for losing to a team that would go on to win 10 games including 3 other ranked foes, in a game where they gave away 4 turnovers). This will be his ninth year now in the upper ranks of college, two of which he spent maturing under Saban. His FAU results speak for themselves in the win column, in the offensive stats, and in recruiting. I am pretty sure his FAU team this year would give us a game.
The dude just got his shots too early in his career to take them properly, IMO. If you look at what he brings to the table, though, he's now made his mistakes and got his experience, he's seen how Saban runs things (and called a record setting offense for him, too) and what a couple of the top destinations in the sport look like, and he's clearly matured a little personally as well, since he seems to finally be weary of the constant celebrity humiliation he received at the center of the sport. He's running a fun, wide open offense that people clearly want to play in, he's recruiting his ass off, and he's building a good program down at FAU right now essentially from scratch. It won't be long before this guy gets another shot at the P5 level, and I think just about everyone who didn't pull the trigger on him is going to be kicking themselves.
