And a Blues team that won a Stanley Cup. Difference of a Perron and Parayko on that team that we don't have. Otherwise, rosters are fairly comparable talent wise. Obviously a top 6 forward and 2nd pair D-Man are not small roster holes, but point remains.
Are they, though? I tried to map the Blues to the Sharks as best I could, and the holes are glaring in comparison.
Just on the defense, I mapped the following pairs - Karlsson/Pietrangelo, Parayko/Ferraro, Bouwmeester/Vlasic, Edmondson/Simek, Dunn/Merkley, Bortuzzo/Benning, Gunnarsson/Nutivaara, Schmaltz/Megna. Looking at that (which I think is about as reasonable a mapping between two dissimilar groups of people as can be) and we're in a much worse hole - Karlsson might be able to match Pietrangelo in theory, but likely won't and will likely miss a third of the season; Ferraro is nowhere near as impactful as Parayko; Merkley is probably not going to be as useful offensively as Dunn that quickly (although I believe he can be a good offensive NHL player); the other guys are all likely a step or more below their counterparts. We're almost certainly in the hole at every single position on the blue line - sometimes by a lot.
When it comes to the forwards, same thing - maybe Hertl can be as impactful as O'Reilly (more offense, less defense), Meier can probably equal or best Tarasenko, Couture probably exceeds Schenn. Outside of them, it's question marks everywhere - will Eklund be as impactful as quickly as Thomas; can Lindblom/Kunin/Gregor provide as much offense as Perron/Maroon/Sundqvist while also equalling their other traits; can Bonino and Sturm prove to be as effective at 3/4C as Bozak and Barbashev (Bonino might no longer be a viable center, for example). I'm skeptical that we get as many goals from the depth options as the Blues did, with the dropoff on the lower lines being pretty big (I'd expect some 30-40 fewer goals).
The goaltending relies on one of our goalies getting really hot. They can do it, sure, but that's unreliable at best, and it's equally plausible that our goaltending takes a step back this year (Reimer should probably not be counted on to be as good).
I think we're a top six forward, a couple of good bottom six forwards, and about five defensemen short compared to the Blues. That's a lot. They were a contender, we're a bottom feeder that will struggle to exit the zone.
