A new season of “A Football Life” begins this week on the NFL Network, with the story of legendary Pittsburgh Steelers defensive tackle, “Mean” Joe Greene. Greene’s Steeler story was not a happy one at the start. Upon learning Pittsburgh had drafted him, Greene admits, “I did not want to be a Pittsburgh Steeler.” But 181 games and 4 Super Bowl rings later, Mean Joe had become arguably the greatest Steeler in history. Tune in this Friday at 9pmEST, only on NFL Network. #pittsburghsteelers #meanjoegreene #nfl #football #nflfilms #afootballlife #nflnetwork
