Seen enough to know Mike Nolan is invaluable; look Jerruh's Big D is as dysfunctional as it is; good coaches hired and are constantly dealing with an owner, son who have a "special relationship with their players"...

That translates to a lot of confusion for players and the chain of command; they end up ignoring, respecting coaches as they'll only listen to the guy signing the checks...

You can even make a converse argument that Dennis Allen, Saints LBers have regressed without Mike Nolan here in the short time he's been gone with that logic; but it's too soon for all except maybe DA...
