This does some serious damage to the Belichick coaching tree with Crennel out also. The other way to look at it, though, and what I believe, is that it reinforces Belichick as the single best coach, maybe ever. It apparently doesn't matter much at all whom he assembles for assistants. Mangini turned out looking like a weak coach with no dominating personality whatsoever, a trait you have to have to be a head coach. Crennel, don't know, not much exposure to him. Does this make Josh McDaniels' stock drop? Again, Belichick is da man!
