The Blackhawks deserve some credit for being a really fucking good team. Probably the best in the NHL. They don't take games off like Pittsburgh and Boston do. It's not that they're so dominant of an offensive team, but they excel at puck possession. The penalty kill has been perfect, and they're the deepest team in every regard.
Everyone in Toronto is weeping, but really, they lost a first round series. They were 12 wins from the cup, and unlikely to be favored in any other round. In all likelihood they would have been promptly dismissed in round 2. I don't feel like what happened to them counts as a great sports heartbreak.
