Craig Morton, a former NFL quarterback who played 18 seasons and became the first quarterback to start the Super Bowl for two different franchises, dies at age 83. Multiple outlets report that Morton died on Saturday. Born in 1941, he played quarterback for the Dallas Cowboys and later the Denver Broncos. With Denver, he led the Broncos to their first Super Bowl appearance, reaching Super Bowl XII for the 1977 season. Morton’s career also included a Super Bowl start with the Cowboys, and the accounts note that he is the first quarterback to take that role for both the Cowboys and the Broncos. The reports focus on his two-franchise Super Bowl milestone and his leadership of the Broncos during their early breakthrough era. His death marks the end of a long NFL career spanning nearly two decades.
