In NHL, it's Clubber Lang vs. Rocky
The Philadelphia Flyers and the Chicago Blackhawks will meet in the Stanley Cup Finals, pitting two of the nation's largest cities against each other with a title at stake.
Across the four major North American sports, Chicago and Philadelphia have met in the postseason 10 times, splitting the series with five wins apiece.
In terms of the championship round, however, Philadelphia holds a 3-1 advantage, winning two World Series and one of two NFL Championship Game meetings. The cities have not met in a championship round since the 1948 NFL Championship Game between the Eagles and the Chicago Cardinals.
However, the fiercest championship matchup between these cities took place inside the ropes

Chicago tough guy Clubber Lang and Philadelphia underdog Rocky Balboa squared off twice in 1982's "Rocky III." In the first matchup at The Spectrum in Philadelphia, Rocky lost his heavyweight crown via a second-round KO to the hungry challenger. Rocky was distraught at the time, having seen his longtime manager Mickey mortally injured by Clubber in a prefight scuffle near the locker rooms. But later, at Madison Square Garden and under the tutelage of former champ Apollo Creed, Rocky returned the favor with a third-round KO of the loudmouth from Chicago.
