week 1: vs. Baltimore Colts

In week 1, the Steelers started #17 Joe Gilliam as he completed 17 of his 31 passes for 257 yards, 2 TDs, and an interception. Gilliam became the first African-American quarterback in league history to play in a game as the designated opening-day starter. The defense held Baltimore to 166 total yards and forced 4 turnovers in the shutout win. (1–0)

week 2: at Denver Broncos

In week 2, the Steelers were carried to a 35–35 OT tie with #32 Franco Harris' running game and #17 Joe Gilliam's 348 passing yards. It was the first regular season overtime game in NFL history. Denver coach John Ralston said of Gilliam that "it was possibly the finest performance I have ever seen by a quarterback." (1–0–1)

week 3: vs. Oakland Raiders

In week 3, after 2 brilliant games by #17 Joe Gilliam, the Raiders came to Pittsburgh for a rematch of the 1973 Divisional Round Playoff game in which Oakland won. However, a fluttering Gilliam completed 10 of his 31 passed which laid the first defeat on Pittsburgh. To make things worse, #32 Franco Harris was injured and would miss the next 2 games. Damp and dark weather hung over the stadium and Terry Bradshaw's relief of Gilliam with a little under 2 minutes left in the game drew cheers from remaining fans. (1–1–1)

week 4: at Houston Oilers

In week 4, the Steelers recovered from the loss at home by beating Houston. #17 Joe Gilliam didn't recover completely; he threw for only 202 yards and 2 interceptions. However, on the game's lone touchdown drive, Gilliam completed 4 consecutive passes. Without #32 Franco Harris, the offense would continuously fall apart. (2–1–1)

week 5: at Kansas City Chiefs

In week 5, the Steelers came away from Kansas City with a 10-point win, 34–24, behind #27 Glen Edwards' 49-yard interception return. The Chiefs used a combined three quarterbacks to throw 7 interceptions. However, #17 Joe Gilliam's play was still deteriorating, and after the horrible performance in next week's game he was benched. (3–1–1)

week 6: vs. Cleveland Browns

In week 6, the Steelers offense continued to flutter with #17 Joe Gilliam's 5 out of 18 and 78 yard passing performance (despite the return of #32 Franco Harris). In the 3 games after the loss to Oakland, the defense forced 15 turnovers, and that is how the Steelers managed to win all 3 games. The front four of #78 Dwight White, #63 Ernie Holmes, #75 Joe Greene, and #68 L. C. Greenwood had become dominant. Together, they became known as the Steel Curtain. After 6 games, the Steelers were 4–1–1, however, the offense was going to need some help if they were to become a contender. In week 7, the Steelers found that help. (4–1–1)

week 7: vs. Atlanta Falcons

In week 7, #12 Terry Bradshaw replaced the failing #17 Joe Gilliam. By 1974, the 5-year veteran was known as the unpredictable and inconsistent quarterback of the Pittsburgh Steelers. He was often overlooked by fans and coaches for making mistakes. It was at this time Bradshaw was going through some emotional problems. He had lost his starting job and fans and players continuously doubted and sometimes mocked him. A failing relationship with his head coach continued to decline. He was often in seclusion at his home as well. Yet, his team did miss him after he watched the first 6 games from the sidelines. However, on a Monday night against Atlanta, Bradshaw returned. The backfield that would start 4 of the next 6 Super Bowls was finally in place. Runningbacks #32 Franco Harris and #20 Rocky Bleier combined for over 200 yards rushing as the Steelers rolled to a 24–17 win. (5–1–1)

week 8: vs. Philadelphia Eagles

In week 8, the Steelers won behind another shutout by the defense that included a 52-yard interception return by #47 Mel Blount. It was one of two career interceptions returned for touchdowns by the Hall of Famer. #12 Terry Bradshaw was still a colt who had not yet been broken; Chuck Noll's patience with him continued to disappear. (5–1–1)

week 9: at Cincinnati Bengals

In week 9, the Steelers lost to division rival Cincinnati, 17–10. The offense was again struggling, and #12 Terry Bradshaw was benched again, in favor of 5-year veteran #5 Terry Hanratty. (5–2–1)

week 10: at Cleveland Browns

In this week 10 matchup, the Steelers defeated the hosting Browns team for the first time in Cleveland since 1964. However, #5 Terry Hanratty completed only 2 of his passes and threw 3 interceptions. He was relieved by Gilliam, and the quarterback controversy had become a real problem for Pittsburgh. However, the rest of the team was playing at a championship level following this madcap game. The turning point came on a miscue in the Browns backfield. Cleveland quarterback Brian Sipe collided with Billy Lefear on the handoff and the ball squirted loose. #74 Joe Greene barged in, grabbed the ball and looked to his left where J.T. Thomas was coming up fast. Greene flipped him the ball and Thomas ran it in from 14 yards out. Earlier in the game, Greene intercepted Sipe and rumbled down to the 14, setting up a Roy Gerela field goal. #32 Franco Harris ran for 156 yards and the defense forced 6 turnovers (overcoming 7 of their own) as the Steelers rallied to defeat the Browns and remain in first place in the AFC Central. (7–2–1)

week 11: at New Orleans Saints

In week 11, #12 Terry Bradshaw was welcomed back into the lineup after the performance by #5 Terry Hanratty. However, in this 28–7 win over the Saints, Bradshaw ran for more yards than he passed. In less than two months, Super Bowl IX was going to be played on the same field. (8–2–1)

week 12: vs. Houston Oilers

In week 12, #75 Joe Greene was allowed to use his new technique called the "Stunt 4–3." He would jump in the gap between the guard and the center, and then blow through the gap. Teams were forced to commit so many blockers to Greene, that his teammates often went unblocked. However, this still couldn't stop the lowly Oilers from beating them 13–10. (8–3–1)

week 13: at New England Patriots

In week 13, #75 Joe Greene became frustrated and threatened to quit the Steelers after losing to the Oilers the previous week. However, he returned for the most important game of the season in New England. With the win, the Steelers would win the division, as well as clinch their third straight playoff berth. The players were nervous and tense, however, the Steelers made quick work of the Patriots, 21–17. The Steeler offense was finally clicking. (9–3–1)

week 14: vs. Cincinnati Bengals

In week 14, the Steelers beat the Bengals in a meaningless game with their offense rolling and their defense dominating. (10–3–1)

AFC Divisional: vs. Buffalo Bills

In this Divisional Round playoff game, the Steelers were described as the only team in the playoffs without a quarterback and were expected to lose at home to Buffalo. The last time the Steelers faced the Bills, O. J. Simpson had rushed for 189 yards and the defense was concerned about him. However, by halftime the Steelers had dominated the line of scrimmage and the offense took time away from the Bills as the Steelers went up 29–7. #12 Terry Bradshaw was in the best game of his career. By the end of the game, O. J. was held to 49 yards rushing in his only playoff game of his career. After three weeks of solid performance by everyone, the Steelers were ready to rematch the Oakland Raiders in the AFC Championship Game.

AFC Championship: at Oakland Raiders

In the 1974 AFC Championship Game, all the hype was centered around the Raiders who had ended Miami's reign in stunning a play that went into NFL Lore as the "Sea of Hands". Raiders coach, John Madden however went a little too far in his praising of both teams when he said that when the two best teams in professional football get together, Miami Dolphins and the Oakland Raiders, great things will happen. Steelers stoic head coach Chuck Noll galvanized the team's spirit by making an unexpected comment. He said that the best team in the NFL was the team in this room. The Steelers would dominate the Raiders in Oakland by using the Stunt 4–3 and stopping the great Oakland offensive line. The Steelers rushed for over 200 yards as the Raiders rushed for a mere 29. Franco Harris ran for the final touchdown and sealed the first Super Bowl appearance in Steelers' history. This game would set the tone for what to come for the rest of the decade.

Super Bowl IX: vs. Minnesota Vikings

Approaching Super Bowl IX, Chuck Noll told his team to go out with no bed check and get the town out of their system. The team had a good time in New Orleans (everyone but #78 Dwight White, who was sick and in the hospital). By Wednesday, they were begging for a bed check. However, that time he gave them and the subsequent responsible attitude was a wonderful way to approach the big game. Noll's approach was in direct contrast to that of Vikings' head coach Bud Grant who had been to two previous Super Bowls, both of which the Vikings lost. The Vikings didn't have a relaxed atmosphere; they were very tense compared to the chilled and relaxed Steelers. Despite the trip to the hospital, #78 Dwight White played and scored the first points in the defensive battle on the first safety in Super Bowl history. The Steelers shut down the Minnesota run game that wanted to attack their opponent's strength the way the Steelers had against Oakland and Buffalo. The Vikings ran 20 times for 17 yards and #10 QB Fran Tarkenton completed just 11 of his 27 passes and threw three interceptions (1 to #75 Joe Greene though he didn't run very far). #32 Franco Harris ran farther than anyone ever had in the Super Bowl to that point, setting a record with 158 yards rushing. He was named the game's Most Valuable Player. The Steelers became champions for the first time in their 42-year history when #12 Terry Bradshaw threw a strike to #87 Larry Brown for a TD.
