You’re out of milk, and to some degree you’re out of your mind. But that’s OK, because pretty much everybody around Boston is a little off the noodle these days. You’re probably not being as focused on your job as you should be, but that, too, is OK. Your boss probably isn’t paying attention anyway. You’re woefully short on sleep. Yet you’re not the least bit cranky. It’s the 2013 Stanley Cup finals that’s causing all this. It’s two great teams. It’s two great Original Six teams. And it’s two iconic American cities whose sports fans are known for their passion, their crazy traditions (Sweet Caroline? Cheering throughout the singing of the national anthem?) and their knowledge of the games they watch. But wait! There’s more! For we are seeing two Formula 1 hockey teams — Boston’s Bruins and Chicago’s Blackhawks — that are chiseled from the same slab of granite. They are so evenly matched that it should come as no surprise that Games 1 and 2 have been overtime thrillers, just as it should come as no surprise that both teams have displayed remarkable resiliency so far. The Blackhawks, who emerged with a triple-overtime 4-3 victory in Game 1, trailed 2-0 and then 3-1 in the contest. Feel free to point out that one of the Blackhawks’ goals came on a Torey Krug turnover, and that another was a ricochet rabbit off the skate of Andrew Ference, and, OK, you can throw it out there that Kaspars Daugavins missed an open net that would have won it for the Bruins. But all of that misses the point, which is that good teams take advantage of lucky breaks and the opposing team’s mistakes. And that great teams devour ’em. And so the Blackhawks, unschooled in the bad art of quit, won Game 1.
