The Denver Broncos were established in 1960 as an original member of the American Football League.
Due to the city of Denver being at a high altitude, and therefore the Broncos stadium being known as Mile High, players will commonly use oxygen machines on the sideline.
Super Bowl Era
In 1983, head coach Dan Reeves traded for quarterback John Elway. Elway led the Broncos to three Super Bowls in four years between 1987 and 1990, with playoff runs highlighted by "The Drive" against the Cleveland Browns in the AFC Championship game. However, Denver fell short each time in the big game, losing to the New York Giants, Washington Redskins, and San Francisco 49ers.
The offense was revamped with the hiring of Mike Shanahan, as Elway was surrounded by skilled position players in running back Terrell Davis, wide receiver Rod Smith, and tight end Shannon Sharpe. The Broncos finally broke though in 1998, winning the franchise's first Super Bowl, and followed suit the next year with another Super Bowl ring in what was Elway's final professional game.
Elway would eventually become a member of the Broncos front office, serving as General Manager since 2011.
After leaving the Indianapolis Colts, Peyton Manning chose to sign with the Denver Broncos in 2012. The Broncos would soon feature one of the best offenses in the NFL, setting multiple records on their way to a 2013 Super Bowl appearance against the Seattle Seahawks, which they lost handily.
Even though Manning became less effective as he aged, the explosive Broncos defense combined with his game management and leadership abilities brought them to another Super Bowl. Denver beat the Carolina Panthers in 2015 to claim their third and most recent Lombardi Trophy.
