Well, not sure if individual achievements or contributions count?
Selke, Pearson, and the Hart all in the same year. Six (seven?) time all-star appearences. 4th among Red Wings players all-time in offensive categories (most anyways). Part of the Russian Five. Third all-time in 20P+ playoff scoring. Dude had 1,180P - that is substantial considering who he played with.
He did have the Fedorov Foundation for children in the Detroit area, which I didn't know existed, so that's pretty cool. Yes, saw this when I looked up his stats.
As for the contract disputes. To me, if I was as good as him (imo, he is still the most well-rounded hockey player I've seen play - the ability to play as foward or defensemen is amazing) I would've commanded a lot of money too. IIRC management also kind of low-balled him the first couple of contracts. I'm not sure where I read that, though it could've been false. Either way I don't have ill will towards him because of those issues. Some might consider that selfish, however I don't. He contributed a crap ton to the organization, and imo (raises shield) his number should be retired.
My favorite things about him were his goal celebrations and how he ALWAYS smiled like a little kid, lol. As a kid I found it awesome everytime - he made me fall in love even moreso with the Wings. And of course the 'white skates', which even further prolonged his greatness.
The kind of player that he was alone makes him a contender as one of the greatest Wings, in my view. Despite the number of goals Ovi has, I don't even think he's nearly as valuable as Feds. Fedorov is the greatest Russian to ever play in the NHL.
