Just asking everyone what about their opinion on the biggest mistakes in NHL history: whether it be a bad trade, coaching, business or on ice mistake.
For me, nothing trumps Pittsburgh's decision to trade their number one pick for Mario Lemieux. Sure, Lemieux was reluctant to play for them, but he was never going to be happy as a Nordique. He posted big numbers in Quebec City, and the Penguins got all three Stanstny brothers, but that wasn't enough to stop the franchise from moving to Hamilton. It took the big trade to the Rangers for Lemieux to get his Stanley Cup rings.
What are everyone else's thoughts?
