Nothing against Dan, but I don't think this would be a good idea. Dan is my favorite NFL player ever, but just because a guy is successful as a player, doesn't mean they are cut out to be a GM. Dan played with a passion and intensity that not many NFL players have, but you also have to be able to evaluate and manage players. You need to be able to scout guys and have players who will fit into the coaching scheme.
Michael Jordan, Isiah Thomas, Larry Bird, Matt Millen....all very good to great players, but they didn't do much when asked to coach or GM a team. Sometimes these great players also have great ego's and they just cannot run organizations. Dan is making $2 million a year working one day a week during the NFL season at CBS.....he wouldn't leave that for less money, much longer work days and more headaches here in Miami.
Oh and in regards to Elway....he ran a very large and successful car dealership and then an Arena League team before working as the Bronco's VP of Operations.
