I dunno, I also hear him say every time, "It starts with me." I don't think he's saying, "The coaches are all good and the players need to step up." More that they ALL need to be better, from him to the last guy on the roster.
Also, I can't remember the last time a team lost a game by 21 points, and I left the head coach's press conference satisfied with what he said about it. You come off a blow out, there's no simple answer that's going to feel good. And I'm not one of those people that needs these coaches/players to get down on their knees and beg my forgiveness for a poor performance. They probably feel worse about it than I do, so what's the point?
Now that I think of it, I don't really need press conferences AT ALL. They really do nothing for me.
