Do you really see McDaniel conceding the AFC East by resting starters? That would surprise me, but they aren't winning that game even with Marino in his prime, the 'Killer Bs' and Larry ***** Csonka, so who knows.
All these losses come down to discipline and details. This is what separates great coaches from the rest of the pack.
McDermott does an awful lot that I've liked, such as embracing analytics and fostering a strong bond within the locker room, but his tenure has run its course. He's at his ceiling and is far too responsible for how often the team has come up small in big moments.
