After the Pittsburgh Steelers became part of the NFL in 1933, they played the Green Bay Packers regularly until the 1970 merger. At the time they joined the league, Green Bay and Chicago were the giants of pro football. The Same Old Steelers lost the first 12 contests against the Packers.
At the time of the merger, they had a more respectable 7-18 record. Since the merger, the Steelers have won 10 and lost 5. The teams’ record of games played in Pittsburgh is tied at 9-9 while the only time they met post regular season, the Steelers lost Super Bowl XLV 31-25.
