NFL Defensive Rookie of the Year, and he was invited to his first Pro Bowl. Former teammate Andy Russell called Greene "unquestionably the NFL's best player in the seventies," saying "No player had a greater impact or did more for his team." Greene and coach Noll are widely credited with turning the Steelers franchise around. The Steelers finished 1970 with a 5–9 record and went 6–8 in 1971. Greene was invited to the Pro Bowl in both seasons. In 1972, Pittsburgh finished 11–3 and won its first division title and its first playoff game—the "Immaculate Reception" game against the Oakland Raiders. During the season, Greene tallied 11 quarterback sacks and 42 solo tackles, and he was recognized as the AP NFL Defensive Player of the Year. Miami Dolphins head coach Don Shula lauded Greene, saying, "He's just a super super star. It's hard to believe he isn't offside on every play. He makes the other team adjust to him."

With the drafting of defensive tackle Ernie Holmes in 1972, the Steelers assembled what became known as the "Steel Curtain" defensive line of Greene, Holmes, L. C. Greenwood, and Dwight White. Greene was invited to the Pro Bowl for 1973, joining White and Greenwood on the American Football Conference (AFC) roster. Greene won his second AP NFL Defensive Player of the Year Award after the 1974 season, becoming the first player to receive the award multiple times. That year, he developed a new tactic of lining up at a sharp angle between the guard and center to disrupt the opposition's blocking assignments. His coaches were at first skeptical of the tactic and did not allow him to try it during the regular season. He first implemented it against the Buffalo Bills in the division championship game. It proved to be highly effective, as it impeded Buffalo's blocking, and running back O. J. Simpson managed only 48 yards rushing. The following week, the Steelers faced the Oakland Raiders in the AFC championship game, with the defining match-up being Greene against All-Pro center Jim Otto. At one point Greene, consumed by emotions, kicked Otto in the groin. Later, on a third-down play, Greene threw Otto to
