I'd love to see the #s backing that up
Great Question. Tried to go back and look at this a little more closely. Its a harder question than I first realized just because sometimes it is hard to define what is success and what category to put people in. Plus external factors(the overall dysfunction of a team) can bring down a good coach.
I will distill this down a little into three main categories: Pro Coordinator(must have no pro HC experience), College HC, Retread(former Pro HC).
2013-2010
Successful Coordinators that promoted
Chuck Pagano - hard to judge his ability since Arians ran the show in year one and he got a Qb prodigy to fall in his lap.
Bruce Arians
Ron Rivera - this could be debated
Gus Bradley
Coordinators that failed
Chudzinski - unfair
Philbin - at this point he is on this list
Dennis Allen - probably woefully underqualified
Leslie Frazier
Pat Shurmur
Mike Munchak
Hue Jackson
Mike Mularkey - technically a retread.
College Coaches that succeeded
Jim Harbaugh
Pete Carroll - I know he is a retread but for all intensive purposes he is a college coach.
Chip Kelley
Failed
Greg Schiano
Chan Gailey - only technically a college HC. he was a primarily a pro coordinator and once pro HC.
Others before my sample
Saban and Spurrier.
Retreads
Succeeded
Fox
Reid
Failed
Shanahan
Fisher
