Breaking: Cowboys first super bowl winner passes away at the age of 77.

The Dallas Cowboys reported to multiple publications on Tuesday that Duane Thomas, a former running back who played a key role in their first Super Bowl victory, has passed away. He was seventy-seven. The reason of death was not disclosed right away. During the 1971 season, Thomas participated in 11 games, 10 of which he started, and ran for 793 yards and a league-high 11 touchdowns.

He also has two touchdowns and 153 yards from 13 receptions. In the 1971 postseason, Thomas contributed a total of 205 yards and three touchdowns, including 95 yards and a touchdown as Dallas shut out the Miami Dolphins 24-3 in Super Bowl VI.

Thomas was also well-known for his outbursts, which resulted in his being traded to two different teams, but he never gave them a report. After rushing for 803 yards in his debut season in 1970, he wanted his contract revised. Over the Cowboys’ postseason run to the Super Bowl, where they were defeated 16–13 by the Baltimore Colts, he gained 313 yards.

Prior to the 1971 season, the Cowboys attempted to trade him to the New England Patriots, but he declined to report. The agreement was nullified by the commissioner, making Thomas a Cowboy.

According to the Dallas Morning News, he didn’t often talk to teammates or the media. I slept six feet from Thomas “Hollywood” Henderson, and he didn’t have much to say, Henderson said in a Tuesday Morning News interview.

He was a man of peace.” Following the 1971 campaign, Dallas arranged a trade with the San Diego Chargers; however, Thomas once more defied authority, missing the 1972 campaign. After being traded to the Washington Redskins, he did report, playing for them in 1973–74 and gaining 442 yards and five touchdowns on 127 attempts.
