The Chicago Blackhawks were flying high until Saturday night, when they got a rude awakening thanks to the Toronto Maple Leafs in a 7-3 loss. If I were a Blackhawks fan, I wouldn't be terribly worried about that loss lingering. Sometimes those things happen in a long season, and the fact Chicago came right back and beat the Los Angeles Kings 24 hours later would seem to indicate things are fine, but games like that loss to Toronto are important because they provide a teaching moment to teams that might not think they need them otherwise.
I say it all the time: The time to coach is when a team loses. When you're rolling like Chicago has been most of the season, the players know everything. Everything's great, they're playing great, the system's great. The players just throw the sticks out there and win. When you lose 7-3, though, that's a good opportunity for coach Joel Quenneville to remind his team to stay focused. In the NHL, no matter who you play, you can never take a night off.
