Here are four takeaways from the Blackhawks' 4-3 loss to the Calgary Flames at the United Center on Monday:
1. Johnny Gaudreau and Pacific Division struggles
Going into the game, the Blackhawks knew they had to be aware at all times of where and when Gaudreau was on the ice. Yet they gave him too much time, and he made them pay.
The NHL's first star of the week scored twice, and both goals came off questionable line changes for the Blackhawks which allowed Gaudreau to have all the time and space in the world.
