Now that Ovi has his cup and Smythe both Sid and Ovi have their legacies locked down. But the worrying thing is a player like Jagr who won 5 art Rosses in a row loses to Sid now very clearly on the polls. Jagr despite everything he did has almost been replaced by Sid in the eyes of the new generation. But the players are different enough that Sid can not damage Jagr's legacy even if some seem him as better.
McDavid and Laine's favorite players are Sid and Ovi. They play a similar style to them. Is there a chance that Ovi and Sid will be looked at as unremarkable in the future because they are dwarfed by Laine and McDavid? Is there a chance that their legacies will crumble? Or are they safe? Or just Ovi? Or just Sid?
I have seen it time and again. They will still get respect but after they have been out of the league for 10 years Sid and Ovi are going to be looked at like Yzerman and Sakic, all time greats but right now people look at Crosby and Ovechkin as being better than they were by a lot. The same thing could happen when Sid and Ovi are just a memory.
The bias of being in the moment has to pass. So in short, while those guys are in their peak, maybe they displace Crosby and Ovechkin for 10 or so years until their time passes and they take their place in history. Maybe not, Crosby and Ovechkin have done so much more than they have, they need do the same things.
On top of that, I can't say how I could possibly know that they won't be better than SId and Ovi, maybe that happens too. I say let's just enjoy watching them play and let history figure that out later.
