Cant' think of one example. I've seen successful coaches take a break and come back and win again (Vermiel, etc.....), but never a stuffed-shirt.
There's a reason why Phillips is standing a post in Palooka-ville as D. Cord. He's had ump-teen chances, in his prime, in a non-FA/Salary cap era to show his stuff and came up wanting.
Before you fall for all this "3-4 defensive genius" crap, consider the following:
First, he may very well be the benificiary of a lot of talent and just held down the fort. Secondly, on a team never known for its defense, as of now it's a one-year wonder. In fact, I didn't know he was still in the NFL until this years Charger defense started getting some press. This has Merriman written all over it. Just on it's surface, any former head coach in the NFL, especially one with multiple teams on his resume' (Norv Turner) who is currently second or third fiddle on some team will only be HC again when someone is stuck with little other choices. It is patently rediculous to assume that this guy is the answer. Where's the evidence? I mean, guys like this are a known commodity. You don't need a crystal ball to dissect Phillips. There's a better shot going with an unknown and hoping you got the next "wonder boy" coach.
This is a frickin' nightmare.................
