I've been following the NHL for a long time and you and I both know that things change. I don't really care what kind of player won the award 30 years ago and I don't really know why you think that's relevant today. The days of players winning purely based on defense are over. Keep hanging on to the past to make a point.
I never said 3rd line shutdown centers are being ignored, I was saying the days of those kind of players getting recognition are over. There's a reason why Couturier finished 2nd this year and his highest previous finish was 8th though this probably wasn't Couturier's most impressive season from a purely defensive standpoint. Then you look at guys like Kesler who have been around forever. He's been a Selke Finalist 5 times in his 13 year career. Is it just a coincidence that the 5 times he was a finalist were also his 5 highest scoring seasons, in order? His Selke win was his best offensive season, his two 2nd place finishes were his 2nd and 3rd best offensive seasons and his two 3rd place finishes were his 4th and 5th best offensive seasons. Any time he's been under 50 points he hasn't been a finalist. I highly doubt he just forgot how to play good defense those years. Kopitar won it this year with 92 points and and 2 years ago with 74 points. last year he barely got any votes and finished 15th while scoring 52 points. Did he take the year off from defense? my point is, the award specifically since the lockout, has been purely the best two-way player. People need to get used to that and stop pretending like offense doesn't matter.
There's a correlation between offense and Selke finishes but this doesn't mean voters actually use offense as a way to compare players when they vote. The more likely scenario is that offense gets attention and people tend to project the idea of players playing well offensively onto other aspects of their game. If Kopitar puts up 52 points, people are going to be talking about how "Kopitar is having a poor season", and that gets projected onto his defense even if he isn't having a poor defensive season. Then the reverse happens when he scores 92. So offense has an impact on the voter's opinions, but it's more in terms of a subconscious influence based on overall play. This doesn't mean voters would compare Kopitar to Couturier and say "Well, I thought Couturier was better defensively this year, but not enough to make up for Kopitar's better offensive game". I very much doubt the majority of voters take offense into account in this way
