Posting articles on opinion pieces isn't evidence, because someone asked the question and it got picked. Hell I bet there is someone out there who thinks Crosby is the greatest Canadian and if they asked the question at the right time, they would get an answer. The links you posted are really not creditable sorry to say. You have two opinion pieces (CBC, ESPN), the head2head site doesn't really say shit (I could do a Crosby/Gretzky one) same as hfboards, I can make up the same debate. Hockey News did its Best players of all time. Gretzky was still #1. TSN did it awhile back, same story.
This thread is about best Canadian, not best hockey player. In the best Canadian debate, Gretzky wins. I'm sorry, but that is not up for debate. I guess my issue is, you are not Canadian, yet are trying to tell Canadians who should be their best athlete based on the fact that you think Orr is better. Unless you live in Canada (just from your posts, it seems you don't) you would really have no idea about the image Gretzky has in this country. When he speaks, people still listen. People are always hunting him down for a comment. Orr not so much, and saying he is shy isn't really an answer. When he came into The Hockey News I was told he was the kindest person, did photos with everyone, signed anything, and was so eager to help in any way he could. But we still don't hunt him down for quotes on major issues unless Gretzky.
I won't debate Orr helping hockey grow in the US, because in his time, hockey was still Canada's game. But does that give him a bonus on Wayne just because he was born earlier? Wayne's trade to LA sparked so much for the sport, grabbed so many headlines, and would be up there in one of the most talked about NHL stories in history. It was ESPN's first film in the 30 for 30 series.
Anyways, as I said, there is no debate on best Canadian athlete. I even find it a little insulting that GSP was put up beside Wayne in the original post. Debating Orr vs Gretzky, well that isn't going anywhere. It will be the exact same when we debate Crosby vs Gretzky once his career is over, and you know it will happen. People will debate the style of the game, the pace, how Crosby has it harder to score, etc.
