Remember how Marv coached defense in Baltimore?

[McC]

He came at you from everywhere, non-stop. He attacked you from beginning to end. He beat you to a bloody pulp. Yes, he had great players. But I'm talking about the way he coached. Bend but not break? Are you kidding me? He would bend and then break you. There were seasons when I worried if the Bengals would even score on them. In either game.

What the **** happened? How did we get from there to here? What broke in that guy that turned him into this guy?
