I checked and the awards are definitely for player of the year, it's not like other awards where what someone has achieved in the past means something. If you think Endler had a better year than Labbe, I'm not going to change your mind and won't even try. I'm on the other side of the fence this year though.
As a few people have mentioned though, the awards are just a popularity contest. I did review the votes for coach and MVP in detail and it was pretty depressing. You can tell right away there is a very large portion of the voting pool who have never seen any of these players even play during the year. And considering one of the best 11 they voted for didn't even play last year, that's about all that needs to be said on that topic.
