The NHL fined the Isles last year $100,000 for the brawl game vs. the Pens, but the Pens did not get fined anything despite a player leaving the bench as a sixth skater to join a fight on the ice - which, by the way, means the head coach should be suspended for one game - he wasn't. But owner Mario Lemieux stated that the NHL didn't do enough to punish the Isles for that disgrace of a game.
Keep in mind that Matt Martin and Trevor Gillies received suspensions. They rightfully deserved them, and Godard got the 10 games required for leaving the bench, but the Penguins didn't receive any other suspensions or fines of any kind.
Lemieux, despite the one-sided disciplinary action, still felt that the league didn't do enough.
