Nicknamed "Super Duper", he played 11 seasons for the Dolphins where his best years came while teamed with Pro Football Hall of Fame quarterback Dan Marino and fellow wide receiver Mark Clayton, the other half of the "Marks Brothers" wide receiver tandem. Duper, who wore #85, was a 3-time Pro Bowl selection in 1983, 1984 and 1986. His best season was 1984, when he had 71 catches, 1306 yards and 8 touchdowns, and in 1986, when he tallied 67 catches, 1313 yards and 11 touchdowns. Duper had four 1,000-yard seasons, with the final one coming in 1991 at age 32, when he posted 1085 yards. In 1990, Duper became only the second Dolphins player to surpass 7,000 career receiving yards. On July 17, 1993, the Dolphins released Duper, after re-hauling their receiving corps bringing in O.J. McDuffie, Irving Fryar, and Mark Ingram Sr., and letting go of the Marks Brothers.
