It's honestly hard to put words to what you're about to see here. At last night's game with the Washington Capitals visiting the Calgary Flames, one fan was spotted violating one of the most storied rivalries in the league by wearing a mashup of a Flames and Oilers jersey.
It's obviously fine to be a fan of the game and watch many different teams, many hockey fans do that. However when it comes to the deepest seeded rivalries in the game, like the Oilers and Flames or the Leafs and Habs, it's almost blasphemous to be a fan of both - let alone make a jersey like this.
