The Broncos were barely competitive during their 10-year run in the AFL and their first seven years in the NFL. They did not have a winning season until 1973. In 1977, four years later, they qualified for the playoffs for the first time in franchise history and advanced to Super Bowl XII. Since 1975, the Broncos have become one of the NFL’s most successful teams, having suffered only seven losing seasons. They have won eight AFC Championships (1977, 1986, 1987, 1989, 1997, 1998, 2013, 2015), and three Super Bowl championships (1997 (XXXII), 1998 (XXXIII), 2015 (50)), and share the NFL record for most Super Bowl losses (5 — tied with the New England Patriots). Thirteen players who have played for Denver are enshrined in the Pro Football Hall of Fame: John Elway, Floyd Little, Shannon Sharpe, Gary Zimmerman, Willie Brown, Tony Dorsett, Jerry Rice, Andre Reed, Terrell Davis, Brian Dawkins, Ty Law, Champ Bailey and Steve Atwater, along with late club owner Pat Bowlen.
