And there has never been a Montreal vs Toronto or Calgary vs Edmonton Heritage Classic.
I love the Winter Classic or Stadium Series has rivals playing in the game:
Detroit vs Chicago - Original Six
Pittsburgh vs Washington - Sid vs Ovy
Montreal Boston - Original Six
Rangers vs Islanders - New York New York!
Philly vs Pittsburgh (2X) - Pennsylvania
LA vs SJ - Cali Baby!
I would love to see an outdoor Heritage Classic with Calgary vs Edmonton!
