I like how they cooled down at the end and just gave up fighting. Maybe they got it out of their system.
I'm play beer-league hockey, and I regularly see such fights. After the initial emotional rush and tussle, 99% of guys want a way out, and the key for us team managers and refs is to provide both sides a face-saving way out.
Then there's the 1% of psychos who don't want to back-away....
