===Pittsburgh Steelers===
{{main|1975 Pittsburgh Steelers season}}

The Steelers became the first official #1 seed to reach the Super Bowl. Playoff seeds were instituted in [[1975 NFL season|1975]]. The Steelers finished the regular season with a league-best 12–2 record, dominating opponents with their "Steel Curtain" defense and powerful running game.  The team finished the season ranked 5th in most points scored (373) and 2nd in fewest points allowed (162). Fullback [[Franco Harris]] ranked second in the league with 1,246 rushing yards and 10 touchdowns, while also catching 28 passes for 214 yards and another touchdown. Halfback [[Rocky Bleier]] had 528 rushing yards, and fullback [[John Fuqua|John "Frenchy" Fuqua]] added 285 yards and 18 receptions. Still, the Steelers had a fine passing attack led by quarterback [[Terry Bradshaw]]. Bradshaw threw for 2,055 yards, 18 touchdowns, and nine interceptions while rushing for 210 yards and three touchdowns. One reason why Bradshaw's numbers were much improved from the previous season was the emergence of wide receivers [[Lynn Swann]] and [[John Stallworth]]. Both saw limited playing time in the previous season, but became significant contributors in 1975. Swann caught a team-leading 49 passes for 781 yards and 11 touchdowns. Stallworth only had 20 receptions, but he had an average of 21.2 yards per catch, recording a total of 423 reception yards.

The Steelers' "Steel Curtain" defense dominated the league, ranking third in fewest yards allowed (4,019) and sending 8 of their 11 starters to the [[Pro Bowl]]: defensive linemen [[Joe Greene]] (future Pro Football Hall of Fame player) and [[L. C. Greenwood]]; future [[Pro Football Hall of Fame|Hall of Fame]] linebackers [[Jack Ham]] and [[Jack Lambert (American football)|Jack Lambert]]; [[Andy Russell (American football)|Andy Russell]], the team's third starting linebacker; future Hall of Fame defensive back [[Mel Blount]]; and safeties [[Glen Edwards (safety)|Glen Edwards]] and [[Mike Wagner]].

Greene made the Pro Bowl despite missing six games with injuries. Linebackers Ham and Lambert and cornerback Blount, who led the league with 11 interceptions and was named the NFL's Defensive Player of the Year, had the best seasons of their careers.  Wagner had 4 interceptions and 3 fumble recoveries, while Edwards had 3 interceptions, while also returning 25 punts for 267 yards.
