Dexter Manley, nicknamed the "Secretary of Defense" a former American football defensive end in the National Football League for the Washington Redskins, Phoenix Cardinals, and the Tampa Bay Buccaneers in an eleven year career from 1981 to 1991. He also played in the Canadian Football League for the Ottawa Rough Riders. Manley played college football at Oklahoma State University.

Manley was drafted in the fifth round (119th overall) of the 1981 NFL Draft by the Washington Redskins, where he was arguably the greatest defensive end in Redskins history and was one of the most feared pass rushers in the NFL during the 1980s. A Redskin from 1981-89, he recorded a team-record 97.5 sacks and a team single-season record 18 in 1986.  That year he also made the Pro Bowl. He also was designated the "Secretary of Defense." In the NFC championship game on Jan. 17, 1983, he contributed to one of the most famous plays in Redskins history, tipping a pass by Cowboys quarterback Gary Hogeboom that Darryl Grant intercepted and returned for a touchdown to punch the Redskins' ticket to Super Bowl XVII, where they beat the Dolphins. Always flamboyant and charismatic, Manley once sported a Mohawk haircut and called himself "Mr. D," a take on the popular actor, "Mr. T," and once wore red and electric-blue Spiderman practice tights.

Officially, Manley had 97.5 quarterback sacks in his career. His total rises to 103.5 when the six sacks he had his rookie year of 1981, when sacks were not yet an official statistic, are included.
