Well that was not a particularly good game on Thursday night, or a particularly good stretch of hockey from the Pittsburgh Penguins over the past week.
I do not have all of the answers to things (or any answers, really) but I do know this: The NHL, NBA, and MLB seasons are far too long to live and die with every game and get angry over every loss, bad game, or even small losing streak. Sometimes you are going to play like garbage for a few games. The good teams eventually figure it out and get it right.
