PAUL MAURO: I thought it was a parody when I saw it. I mean, what's it going to teach you about?  To show up late? You know, to me, this is like hiring the coach from a last place team. All right. And full disclosure: I was up there. I'm a graduate of The Kennedy School. I know it's in vogue to bash the Ivies, etc., but they have some terrific people, great professors, and wonderful programs. I don't expect Bill de Blasio to be among them.
