Interesting article on how Gruden prepares for broadcasts and his attention to detail. He has a collection of tapes that cover just about every play that he uses to understand tendencies and prepare for gameday. As the head of the fired coaches association he uses those to coach other as well. Zeke and Eli are mentioned in the article. I can see why his name comes up when a HC position opens, and while he doesn't say he won't return to coaching he seems to love his current gig.
