On October 9, 1979, a contract dispute forced the Colts to trade John Dutton to the Dallas Cowboys. Dutton moved to left defensive tackle alongside Randy White, establishing a formidable defensive line that also included Harvey Martin. He was part of the 1985 defensive unit that holds the Cowboys' single-season sack record (62). During his 9 years in Dallas, he helped the Cowboys reach the NFC title game three straight years (1980, 1981 and 1982). He may have been the best Cowboys defensive lineman to have never won a Super Bowl ring. John Dutton has hand signed this Dallas Cowboys B&W 8x10 Photo.
