Immediately after, Erik Gudbrandon moves in to defend his younger teammate, and throw down with Kostin. The two obliged the fight, and it was a heavy one - both players landed strong punches before the referees stepped in to break it up.
The fight fired up both benches, and a message was clearly sent to both sides. It seems, in this opening week, that the prevalence of fighting may be making a return to the NHL, as players know it clearly as an intangible benefit to the team, and their fans.
