The
Pittsburgh Steelers franchise was one of the most downtrodden in the NFL, having experienced many losing seasons before the hiring of
Chuck Noll as head coach in 1969. Noll and the
Rooney family, which had owned the franchise since its formation, agreed that building the defensive line was crucial to rebuilding the team. Thus, they decided on Greene with the fourth pick of the
1969 NFL draft. The selection proved unpopular with fans and media, who were hoping for a player that would generate excitement; the relatively unknown Greene did not appear to meet their expectations. Meanwhile, Greene, who was highly competitive, was disappointed he was picked by a team that had such a reputation for losing. Noll saw immense potential in Greene and insisted on drafting him.
Ken Kortas, who had played in all 42 games as defensive tackle over the previous three seasons, was soon traded away to the
Chicago Bears to accommodate him on the roster. In a matter of months, Greene established himself as one of the most dominant players in the league at his position. Despite his team finishing
1969 with a 1–13 record, the
Associated Press (AP) named Greene the
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." By this time, Noll had built a formidable defense. "We have maybe 10 guys now capable of making All-Pro," said Greene in 1972. "I'm just like all the other guys, doing my best in a team effort." 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 which he called the "stunt 4-3". His coaches were at first skeptical of the tactic and did not allow him to try it during the regular season. He first implemented the "stunt 4-3" 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. Oakland was held to 29 rushing yards in the Steelers' 24–13 victory. On January 12, 1975, the Steelers won their first of four
Super Bowl championships in a six-year span by defeating the
Minnesota Vikings 16–6 in
Super Bowl IX. In that game, lined up against center
Mick Tingelhoff, Greene recorded an interception, forced fumble, and fumble recovery in what is considered one of the greatest individual defensive Super Bowl performances. Pittsburgh limited the Vikings to only 119 total yards of offense, 17 of which were gained on the ground. After the season, Greene was honored by the
Pittsburgh Post-Gazette at its 39th
Dapper Dan dinner as Pittsburgh's outstanding sports figure of the year. Walk of Fame Greene missed four games in
1975 due to a pinched nerve, snapping a streak of 91 straight games started since he entered the league. After leading the Steelers to another Super Bowl win after the 1975 season over the
Dallas Cowboys in
Super Bowl X, Greene missed the first several games of the
1976 season with a back injury. The Steelers started off the season 1–4 and looked like they would not make the playoffs. Quarterback
Terry Bradshaw was also injured and was replaced by rookie
Mike Kruczek. Greene returned and the Steelers defense carried the team to nine-straight wins and the playoffs. With a defense considered one of the best in NFL history, the 1976 Steelers held opponents to an average of less than 10 points per game (138 points over 14 games). During their nine-game winning streak, the Steelers defense recorded five shutouts, including three straight, and surrendered a total of 28 points (roughly 3 points per game). The defense allowed only two touchdowns over those nine games. The Steelers were defeated by the Raiders in that year's AFC championship game. By
1977, Greene was the captain of the Steelers defense, although his reduced effectiveness over the previous two seasons due to injuries led to rumors that he was washed up. He was never again able to attain the same success as a pass rusher after his pinched nerve in 1975. In that contest, Greene had one of Pittsburgh's five sacks of Dallas quarterback
Roger Staubach. Pittsburgh finished the
1979 season with a 12–4 record, and ranked second in
total defense and fifth in scoring defense. Greene was named a first-team All-Pro by the
Pro Football Writers Association and
Pro Football Weekly and was invited to his final Pro Bowl. Pittsburgh then defeated the
Los Angeles Rams in
Super Bowl XIV for an unprecedented fourth Super Bowl title. With the fourth title came Greene's fourth
Super Bowl ring, inspiring his famous phrase, "one for the thumb", an allusion to winning a fifth championship. His wish went unfulfilled, however, as the Steelers failed to reach the playoffs in each of his final two seasons. He finished his career having played in 181 out of a possible 190 games, and recorded 77.5 sacks ==NFL career statistics==
