You guys are hyper fixating on that point, his original point was simply that our current squad doesn't have any elite or game-breaking talent at any position, and becuase of that, there isn't much point in going after a Sanheim, since while it's an upgrade, it won't significantly move the needle to make us contenders.
I think we can argue that Buchnevich is that elite talent, and the counter to this is his health and contract future. Will he be around when Dvorsky is developed, and can he play a full season consistently.
The 2019 club had ROR and Petro has bonafide elite players, and then we had players/pairings performing at elite levels, Binnington and Bouwmeester/Parayko.
I can take an argument that Sanheim/Parayko could get back to what Bouwmeester/Parayko did, but Bouwmeester defensively is ahead of Sanheim IMO, but I can see the argument that they can get back to elite level defense as a pairing.
Kyrou certainly has Tarasenko type potential in terms of game-breaking ability, can argue he's already there, the issue is more his consistency. Tarasenko wasn't great defensively, but he was rarely a liability, and at times he was very strong defensively, one of the goals in game 7 was a direct result of his defensive play. That's what we need Kyrou to get to. At times he uses his speed as a defensive asset in taking pucks away, and that needs to continue.
At the center position, we need Dvorsky to hit and be a Kopitar/ROR, and Thomas needs to be able to drive the offense against top competition. I'm big fans of both, but if neither become elite, even in a specific area of the game, we do run the risk of becoming a pretender where we have a lot of good parts, but never good enough to get over the hump. Look at teams like the Jets and Wild.
