Harbaugh's first Stanford coaching staff has produced 5 head coaches

That's pretty amazing, especially considering how weak that program was at the time that staff was put together.  You would have to assume Drevno will make it 6 within the next couple years.

5 head coaches and 0 jive turkeys

But I think there's going to be a lag of 10 years or so, for these players to attain the age they work their way up to D1 ball (and maybe retire from the NFL!!).  I think when you play for Harbaugh you love the game (and the work required to get better and better at it) and aren't there for the weightlifting or the social status bump on campus.

I don't know who they are yet but I believe we will recognize these names very easily in the future.

My super secret hope is that Drevno just hangs around Ann Arbor foreva, becoming the successor to Harbaugh someday as the HC in true Gary Moeller fashion.  If he gets bored we can always put him on defense to broaden his skill set.

Dereck Mason at Vandy and Brian Polian [formerly] at Nevada as well. 

Five of Bo's first group of assistants became head coaches. Eleven of his assistants during his first decade became head coaches, and by my count he had fifteen overall during his Michigan tenure. I might have missed one or two.

Four of his assistants—Carr, McCartney, Miles, and Nehlen—took their own teams to the national championship game, with the first three winning.

Moeller inherited Bo's staff, and he was HC for just four years so he didn't have much of an opportunity to put his own stamp on his staff.

Carr had three in his coaching tree—Hoke, Debord, English. Stan Parrish was also a Carr assistant who went on to be HC at Ball St and interim HC at EMU, but Parrish had previously been HC at three different schools before joining Carr's staff so I wouldn't call him part of Carr's tree.

Only one of RR's assistants at Michigan has ever been HC, but that was Greg Robinson, whose disastrous tenure at Syracuse prior to joining RR was the the worst in Orange history.

None of Hoke's assistants have become HC, and right now it's difficult to envision any of them doing so.

Derek Mason was not on that staff but is another for Harbaugh's tree. Crazy good. 

It'll be quite a bit more before he's all said and done. 

Drevno and Fisch are probably heading somewhere in the not so distant future. Wheatley and Harbaugh Jr. could as well, but they've definitely got to prove themselves at a coordinator level before they take that kind of jump to HC. Brown could probably have most any job he wants if he were open to looking. Thank the good lord he's "too damn old" for that. 

That's one of the many things that absolutely baffled me about Carr. The guy had almost no coaching tree to speak of. And the guys he did send off into the wild blue yonder turned out to range somewhere from average to awful.
