I miss the guy, he understood marketing and what the fan wanted more than any player during his era. Plus the whole fight for marriage equality is great, homophobia is a plague in professional sports and while he didn't directly took a stance on homophobia in sports itself, it's refreshing to see someone like him getting in the cause. Plus you know, he was playing some good hockey for us.
Sean Avery was a player who was good in the right doses. The problem was that he could not be kept in line---and in a way, I think that the Rangers mishandled the Avery situtation; they could have loaned him to another team's AHL affiliate while he was with the Whale instead of leaving him off the Clear Day roster and ending last season early for him.
He was one entertaining character and one of the best ever at what he did. More importantly he was an effective player who contributed positively to this team. But there are many valid reasons why people dislike him to the degree that they have to enter threads about him just to complain about him.
Sean is a complex guy. He can do some very good things and some pretty bad things in his life. There are things about Sean that are likeable and things about him that are not likable. Some people in this world just like to annoy other people. Look at how many trolls online get off out of annoying other posters. Sean did not just try to annoy opposing players. He had had disagreements on and off the ice with his own teammates, coaches, announcers, etc on multiple teams. Sean fans (I used to be one) see things the way Sean sees them. Like Sean voluntarily decided to move on to other things. The truth is closer to very few if any NHL teams want him.
