There is a lot of history between the Pittsburgh Steelers and Philadelphia Eagles. Whether it was the time when the two organizations joined during the war effort, forming the Steagles, or the fact Pittsburgh hasn't won in the city of brotherly love since the 1960s.
On top of being cross-state rivals, the two teams haven't both been undefeated when facing one another since the same time as Pittsburgh's last win in Philadelphia. With both teams 2-0, most would think this game is about as even as it can get, but the truth of the matter is these two teams are viewed as completely different 2-0 teams.
