3. Craig Morton
The New York Giants couldn’t wait to get rid of Morton, trading him to Denver straight up for Steve Ramsey. Other than acquiring John Elway, it may be the best trade the Broncos ever made. Morton led Denver to the Super Bowl in his first season with the team (1977) and the Broncos have been among the NFL’s winningest franchises ever since.
It was Morton, not Hall of Famer Roger Staubach, who started for the Cowboys in 1969, 1970 and 1972, including a Super Bowl appearance. Staubach finally became the full-time starter when Morton was shipped to the Giants in 1974. His 8-25 record with the talent-starved Giants led to his trade to the Broncos.
