The 1985 season marked the beginning of on-going contract disputes between Dickerson and the Rams. In 1987, after playing just three games for the Rams during the strike-shortened 1987 season, Dickerson was traded to the Indianapolis Colts in one of the NFL's biggest trades ever at that time. In a three-team deal, the Colts traded linebacker Cornelius Bennett, whom they drafted but were unable to sign to a contract, to the Buffalo Bills for their first-round pick in 1988, first- and second-round picks in 1989, and running back Greg Bell. The Colts in turn traded Bell and the three draft choices from Buffalo plus their own first- and second-round picks in 1988, their second round pick in 1989, and running back Owen Gill to the Rams for Dickerson. With the picks the Rams took running back Gaston Green, wide receiver Aaron Cox, linebacker Fred Strickland, running back Cleveland Gary, linebacker Frank Stams, and defensive back Darryl Henley. The trade reunited Dickerson with Ron Meyer, who had left SMU after Dickerson's junior season to take the head coaching position in New England and who was hired by the Colts in 1986 following Rod Dowhower's firing.
