Craig Morton, the Hall of Fame quarterback who led the Denver Broncos to their first Super Bowl appearance, has died at 83.

Morton was instrumental in the Broncos' historic 1977 season, guiding the team to a 12-2 record and playoff wins over the Pittsburgh Steelers and the Oakland Raiders. He was named AFC Offensive Player of the Year and Sporting News Player of the Year.

"To me, he's the most valuable player in the National Football League," fellow Bronco Haven Moses said after Morton earned the MVP award in 1977.

Morton played for the Broncos from 1977 to 1982, throwing for 11,895 yards, the most in franchise history at the time. He also led the team in pass attempts and completions.

Before Denver, Morton was drafted by the Dallas Cowboys in 1965, starting his career with 10 seasons and 10,279 passing yards. He also played for the New York Giants.

Over his 17-year NFL career, Morton threw for 27,908 yards and 183 touchdowns, posting an 81-62-1 record across 207 games.

The Broncos confirmed his passing on Saturday, paying tribute on social media.
