The Chicago Blackhawks biggest weakness all season long was their defense, and if you don’t believe that first statement just remember that David Rundblad played in Games #5-7 after taking a sabbatical across the pond for most of the season and not having played a game with the Chicago Blackhawks since 2015.
The defense was the biggest issue which made you scratch your head every time that Joel Quenneville said that he was fine with his defense. The last issue to come up with the Chicago Blackhawks defense was in Game #7 when Erik Gustafsson turned the puck over instead of giving the puck to Patrick Kane or Artemi Panarin, and before you knew it Troy Brouwer had three whacks at it to score.
