I agree although with the same group of players you have to wonder how much difference a new coach would actually make. I guess it would depend somewhat on what kind of relationship the guy coming in already has with the officials.
I think that has a big impact. Usually a team like the Canucks starts to get more calls as they get better and win more. Look at Detroit - they're still riding their reputation as a good team and they get away with murder.
Considering that everyone knows the Sedins are good guys I always wondered why the team had so little pull with the refs. Obviously players like Lapierre and Kesler don't help but other teams have had those types of players and have overcome their reputation or at least their stars got favourable calls even if the annoying pests didn't.
Maybe AV had a bad relationship with the refs, who knows? This one is just a guess on my part but it would explain a lot.
