Coleman was selected by the Dallas Cowboys in the eighth round (208th overall) of the 1972 NFL draft.[1] The Cowboys saw great potential and he became the first African-American linebacker to make the team in franchise history.
He started the year in the taxi squad, before being promoted to the active roster after Chuck Howley was injured. He played mainly on special teams, including the playoffs.
After not agreeing with his playing time and contract numbers, he forced the team to trade him to the Houston Oilers in exchange for a conditional draft pick (not exercised) on July 13, 1973.[2]
In 1988, he was first convicted of the murder of a Greenville nightclub bouncer and sentenced to life in prison. The state Supreme Court overturned that verdict and granted Coleman a new trial. In February 1990, the jury failed to reach a verdict in his second trial. In November 1990, he was convicted of murder in his third trial. Coleman is serving his life sentence for murder in a South Carolina state prison. He was a suspect in several other homicides in the state but not charged.[7]
In 1993, he appeared in a film produced by the U.S. Department of Justice entitled "Hard Choices: Inside Looking Out". The film presents the story of two fictional teenagers confronted by the temptation of drug use, who are advised by two former professional athletes (Coleman and Alex English).[8]
