Denver Broncos
Gary Kubiak only coached the Broncos for two seasons but he won a Super Bowl. The franchise lost patience with John Fox after he came close to achieving glory. Ultimately, Kubiak got enough juice out of Peyton Manning to bring the Vince Lombardi Trophy to Mile High City (via SBNation).

Meanwhile, it’s a tie between Josh McDaniels and Nathaniel Hackett for the worst coach in their recent history. The former cheated and made terrible roster decisions. Hackett simply didn’t have the chops at the highest level and wasted Russell Wilson’s first season under center in Denver.
