The thing is, I think the uniqueness of the Sedins' possession style papered over a lot of flaws the teams behind them had.
I mean, from 09-12 they had a strong supporting core.
But their breakout began in 05-06 as Nazzy and Bertuzzi were crumbling. Then 07 they had Luongo and a solid D and basically nothing else.
From then until 08 they had to try to turn Pyatt and Bernier into top liners.
They were often played with our shitty 3 D pairing in order to protect them from being exposed.
Then from 2012-2018 they really weren't given much to play with.
I also think that Rick Nash doesn't deserve to be mentioned in the same paragraph let alone sentence.
And I would argue they are definitely top 200 NHL players. Not that you need to be exhaustive, but give me 5 or 10 players you think aren't in the top 100 but ARE in the top 200 who are better than the Sedins?
Even as you walk through each period of time, that's pretty decent support. I don't think the team actively held them back until their mid-30s and, even then, they were also slowing down themselves. Yes, it did take them a while to find a linemate in Burrows but there were still two of them on the same line, which is more than a lot of stars have. In the cap era, it is very rare to have three elite players on the same line. Crosby played with Kunitz/Dupuis throughout his prime, Malkin was saddled with even worse linemates (and won a Smythe playing with Fedetenko), Datysuk was attached at the hip with Abdelkader and Kane played more often with guys like Kruger, Bolland and Anisimov than Toews.
The Rick Nash comparison was just to bring up a player who was truly on an island with no support. Iginla is probably a better comparison. His best centers, pre-Crosby, were Craig Conroy and Langkow.
And Iginla is a player I'd bring up that qualifies as a guy likely outside the top 100 that's in the top 200 but better than the Sedins. Off the top of my head, it would be guys like Kopitar, Karlsson, Stastny, Perreault, Kariya, Modano, Bucyk, Bure, Datsyuk, Leetch, Hawerchuk, Doughty, Zetterberg, Keon, Stamkos, Recchi, Savard, Bergeron, Sundin, Gilmour, Francis, Oates, St. Louis, etc. That said, I don't think the Sedins would be out of place in a top 200 but they're certainly not locks.
At the end of the day, as far as I'm concerned, they had a pretty decent environment for success. Was it optimal? No but only a few players get lucky enough to find themselves on a late-90s/00s Detroit or Habs dynasty. But they enjoyed a lot of winning in the regular season and came damn close to a Cup. You could do a hell of a lot worse (just ask a guy like Marcel Dionne) and most players really only get a few windows where their team is a contender. I also wouldn't have begrudged them if they went Cup-chasing in their later years but it would have been because the team was past it's best before date, not because the Canucks did them wrong.
