There was an NFL Films presentation last night that I have not seen before. It was called "The Ray Lewis Coaching Tree", and it was six coaches that had been on the Ravens roster as coordinators and went on to be head coaches in the NFL.
The Ray Lewis coaching tree: Part I
If you really want to see what Ray Lewis is about, see these men talk about him. It was an excellent documentary, and the insight they provided clearly revealed that Ray is not an act. He's the real deal.
