5 teams the Pittsburgh Steelers have the worst record against in NFL history

The Pittsburgh Steelers are one of the most winning franchises in the history of the NFL -- both in terms of their post-season success and overall win percentage. But for some reasons that are hard to explain, there are a few teams throughout history who have simply had their number.

For whatever reason, Pittsburgh seems to struggle against certain teams -- most of which are uncommon opponents. Even when these opponents aren't considered good teams, they can still be a challenge to deal with. Here are five teams that the Pittsburgh Steelers have the worst record against of all time.

5. New York Giants

The New York Giants have been in the NFC since the AFL-NFL merger in 1970. Since then, these two teams have only faced each other 11 times. However, the Steelers and Giants are two of the most historic franchises in all of sports and they have a history that dates all the way back to the beginning of Pittsburgh's football team was first assembled in 1933.

Over the past 90 years, the results have not been kind to the Steelers in this head-to-head matchup, as they have a record of just 31-44-3 when facing the Giants. Things look worse than they have been in recent years though. To begin their rivalry, Pittsburgh started 2-14-1 against New York before this competition seemed much more even.

In recent years, the Steelers have fared much better as they have won 5 of their last 7 contests against the Giants since 1994 -- including a current three-game winning streak. These two teams haven't been rivals for a long time, but history shows that this matchup has always been one-sided.

Perhaps Pittsburgh can even the score, given enough time. As of now, however, the Steelers have one just 41.7 percent of games played against the Giants in a matchup that has been around for nearly a century.
