The Pittsburgh Steelers' four Super Bowls in the 1970s were fueled by more than star power.

Sure, the highlight films of those seasons are filled with clips of the team's nine hall-of-famers rising to the occasion, whether it was Terry Bradshaw throwing bombs to Lynn Swann and John Stallworth or Joe Greene tossing a running back for a loss.

But the team's elevation to one of, if not the greatest dynasty in the history of the NFL, included a lot of other players turning Chuck Noll's strict attention to detail into dominating play on the field.

Sam Davis was one of those who, while not enshrined in Canton, played a key role in Pittsburgh's fortunes. An offensive guard, he was one of 22 players to earn four Super Bowl rings with the team.

Davis died last week at the age of 75, causing me to think long and hard about Steeler players from that era who don't have busts in the hall of fame. Naturally, I ended up ranking them and the results follow.

I focused only on the players who contributed to all four Lombardi trophies, so no Andy Russell, Glen Edwards, etc.

— One of the few players of that era to arrive in Pittsburgh before Chuck Noll, Bleier was wounded in combat in Vietnam and was told his foot injury had ended his playing career. But he battled back onto the field — a story documented in his book “Fighting Back” and the subsequent movie.But he was more than just an inspiration to his teammates, he produced on game days, too.Bleier became a reliable backfield mate to Franco Harris, rushing for 528 yards in 1975 and 633 yards and five touchdowns in 1978. In Super Bowl XIII against Dallas, he scored the go-ahead touchdown on a pass reception just before halftime.

— A two-time Pro Bowl selection, Wagner never came up bigger than in the 1975 postseason. He intercepted Oakland quarterback Ken Stabler twice in a 16-10 win in the AFC Championship. Then in Super Bowl X, he picked off Dallas' Roger Staubach early in the fourth quarter with the Steelers nursing a 12-10 lead. The turnover, which Wagner returned inside the Cowboys 10, led to a Roy Gerela field goal.

— He played tight end on Pittsburgh's first two Super Bowls, then tackle on the last two. He caught a touchdown pass late in Super Bowl IX and started at right tackle in Super Bowl XIV against the Rams, helping Bradshaw win MVP honors with 309 yards and two touchdown passes.Noll once said in an interview that of his players from the 1970s not to be in the hall of fame, Brown was most-deserving.

— He became a starter in 1977 and developed a reputation as one of the hardest-hitting defensive backs in the game. As effective in rush defense as he was against the pass, Shell broke several of Earl Campbell's ribs with a hit on Monday Night Football in 1978, the same year he made his first of five Pro Bowls.

— Pittsburgh's all-time sack leader until Jason Gildon came along, Greenwood was part of the Steelers' famed Steel Curtain front four, along with Joe Greene, Ernie Holmes and Dwight White.Greenwood sacked Staubach four times in Super Bowl X. A year earlier, the 6-foot-6 end batted three Fran Tarkenton passes in what is, to date, the most dominating defensive performance in Super Bowl history as Minnesota managed just 119 total yards.Derek Pyda is a staff writer for the Butler Eagle
