I was at a graduation party over the weekend, and had a chance to catch up with a friend I hadn’t seen in a while. He wanted to talk hockey. So we discussed the current playoff situation for a bit, and then reminisced about the old Chicago Stadium and legends Stan Mikita and Bobby Hull. But it was one statement my friend made that really hit me. “Hockey is so great!” he said. “Is there any other sport where you can substitute players without stopping the game?” Well, I’m hard pressed to think of one.
