It depends who youre ranking against when youre talking about Kelly though. Identifying with the leafs definitely knocks him down in discussion, but like I said, he wasnt identifying with Mike Illitches Red Wings either. Theres enough history to kock him down, but him being knocked down puts him somewhere still likely ahead of Zetterberg for me, or right ther beside him. Its not like I'm putting him above Howe or Yzerman.
Even with Kellys time as a Leaf, he still played almost as many seasons with the wings as Zetterberg and accomplished far more in that time. To have him ahead isnt a slight on Zetterberg, like you said theres a lot of history. To have Zetterberg ~10, right near a top ten all time dman isnt a slight against Zetterberg.
And now this is going to sound like I'm talking **** about Zetterberg but its context. You talk about how much history the wings have but what has Z done to be considered ahead of some of these guys. He has his conn smythe and wore the C. But he never won anything as the captain, he won one cup, he didnt even break 1000 points in his career, barely broke 1000 games. Playing devils advocate obviously because I love Zetterberg but like you said its a team with a lot of history. Sure maybe rank him above Kelly (I dont agree but see your argument), but how can you defend that stat line as top 5 wing all time? Above someone like Ted Lindsay like has been mentioned in this thread.
I think I take Jack Adams into account more than most when considering these lists, but still, Zetterberg doesnt belong over a lot of guys, the wings have an insane history and likely the hardest team to get your jersey retired on. I really wouldnt be surprised if Zetterberg didnt get his retired, hes right on that cusp.
