The NFL is a game of who you know. Offseason moves by players and especially coaches are so often dictated by connections to others in the league. The Broncos are a prime example as they’ve developed and found success with coaching staffs and players with close ties. Consider 2015, when the team parted with head coach John Fox, and the top candidate to replace him was Gary Kubiak, the former Broncos coordinator and Mike Shanahan understudy who helped John Elway to two Super Bowl titles in the late 1990s.
