Renck: So much attention has been paid to the Broncos’ surprising playoff berth last season that it has left little time for hand-wringing about a sobering reality: they haven’t accomplished anything. Sean Payton did not leave the golf course in Coeur d’Alene and the set of Fox Sports to go the postseason, something he accomplished nine times in New Orleans. Keeler: The Chiefs can be had. Most importantly, Payton knows it.
