It's the playoffs, so you'd expect hard hitting and physicality to be the norm.
It seems the referees in Boston tonight disagree. Apparently this is a roughing penalty on Dion Phaneuf.
Huh. Okay then.
Don't worry. Brad Marchand wasn't laughing for very long. Just eight seconds into the power play, he was called for "tripping."
At least the referees are doing a good job of policing themselves?
