He was quite an important part of this team's success (yeah, even when there were better players than him, like Scotty Stevens) and maybe someday #27 will go to the rafters (Lou doesn't have to do it... it may as well happen 20 years later with another GM - Montreal retires numbers of 70-year old guys...). And if he chooses to change the team, let it be. But he is no longer a part of the organisation, he's an Anaheim Duck now and I don't care much about him - that's why I definitely wouldn't cheer him. But I wouldn't boo him either - he's not a slave, he can choose where he wants to go and unless he chooses Rangers or Flyers, he can do that.
And when it comes to this whole retirement thing... Yeah, that was quite classless and irritating, but I didn't think much about him - it wasn't about our team, it was about a guy playing on the opposite end of North America, I could care less what he does: he's not a player of ours.
Unfortunately, I won't have the opportunity even to sit on my hands, because I live on a different continent. Have fun, guys, I'm looking forward to this Anaheim game.
