Former Pittsburgh Steelers running back Mike Collier died in Maryland on Sunday, according to an online obituary.

Collier, who won Super Bowl X with the Steelers in 1975, was 71 years old. No cause of death was announced.

“It used to seem like a dream,” he told the Baltimore Sun in 2013 of his time in the pros. “I realize that a lot of people would love to have been in my position. I thank God that He gave me the opportunity to be there.”

Collier played at Morgan State University in Baltimore before he was selected by the defending-champion Steelers in the 14th round of the 1975 NFL Draft as a running back — though he was more known as a kick returner in college.

“All I asked for was a chance,” Collier recalled in 2014. “Being in the NFL and having that chance was the greatest thing. Luckily, there were six preseason games then. A couple guys got hurt – nothing too serious but it gave me a chance to play and prove myself.”

In his first regular season game, Collier scored a seven-yard touchdown in a 37-0 rout of the Chargers. It was one of three touchdowns during the season.

The Steelers repeated as AFC champions, setting up a classic showdown with the Cowboys in Super Bowl X.
