Drew Brees endorses Aaron Glenn as his top pick and Klint Kubiak as his in-house hire

Employed mostly. But outside of Campbell and Glenn, nobody else has moved up and been successful unless you count DA when he was just the DC here. But that's one successful HC, maybe two successful DCs, and a bunch of failed offensive guys like Marrone and Lombardi.

So some success but far from everything he touches turning to gold.
employed is staying relevant in the NFL.
