The Philadelphia Eagles and the Pittsburgh Steelers have had a vast history as members of the National Football League (NFL). Below is a list of their similarities:
- Sister cities in the state of Pennsylvania.
- Began as teams with different names – Philly was the Frankfort Yellow Jackets while Pittsburgh was called the Pirates.
- Initially played games under Pennsylvania Blue Laws which meant neither team could play a home game on Sundays. Both clubs entertained home games on Saturdays or played on the road for Sunday contests.
- Both became NFL franchises in their current city in 1933.
