3. John Fox
The Denver Broncos replaced the disaster known as Josh McDaniels with John Fox at the beginning of the 2011 season, and things went incredibly well. In fact, Fox had one of the most impressive four-year runs in the history of the league.
Fox rolled deep with four division titles and three times reached the conference championship game including a Super Bowl appearance in 2013. Denver was trounced in the game, something that reportedly soured the relationship of he and general manager John Elway. Elway no longer was sure if Fox could get the job done but gave him one more year to prove himself. The Broncos would lose to the Indianapolis Colts in the divisional round and the next day, Fox was gone.
Many people attribute Fox’s success to the arrival of Peyton Manning, but Fox won a division and a playoff game with Tim Tebow, one of the worst quarterbacks of all-time. Fox also had a lousy defense to work with most of his tenure and a questionable offensive line, yet worked around it all. If that doesn’t convince you that Fox is a terrific coach, the guy got Jake Delhomme to a Super Bowl. Jake Delhomme.
Denver hired Gary Kubiak to replace him, and let’s just say that is not overwhelming. Denver is 11-4 but averaging about 2.5 points per game and looks ripe to be pounded in the playoffs.
