It's a wolf v2.0
The Sedins have been perennially high-scoring forwards, and are very good players, but most years they have not been "Art Ross material" either. Not if you define that as being a threat to actually win the scoring title in a given year.
And anyway, I don't think anyone can expect Benning to come away with not one but two high end forward prospects - and that's not exclusively an indictment of his performance as GM so far, it's just really hard to replace consistently great players. Honestly it probably won't happen for quite some time, and if this team is going to be good it will have to be good in a different way. But most likely, they will just be a mess for some time after Henrik and Daniel hang them up.
The other option, a little less certain but if you're patient it can be viable, is to build up prospect depth and maintain a good amount of cap space so when another teams star player hits the trade market (1 or 2 get their every year) you're well positioned to pounce.
And this is something that Benning is playing horribly. He's wasting our prospect depth on borderline players like Marcus Granlund and hitting committing us to the cap ceiling with guys like Miller/Sutter/Dorsett/Sbisa.
We're not even in the position right now to trade for a Jacob Trouba or Tobias Reider, never mind a legit 1st line/top pairing skater.
