Since 1975, the Broncos have become one of the NFL's most successful teams, having suffered only nine losing seasons.[8] 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). The Broncos have eight primary members enshrined in the Pro Football Hall of Fame: John Elway, Floyd Little, Shannon Sharpe, Gary Zimmerman, Terrell Davis, Champ Bailey and Steve Atwater, along with late club owner Pat Bowlen.[9]
