depends on the goal. If it's a complete tear-down (don't think they need that) versus a coach who can get this team to play to maximize their potential (like Trotz did). No matter who they choose, there will be question-marks/risk.
I like the core of the team, just not sure where to get 1-2 elite forwards, though some aging ones may be available as UFAs OR if you want to chase players like Horvat/Meier/JT Miller or possibly a guy like Nylander who'll be tough to re-sign. Pastrnak will find a way to land in Boston because they are Boston.
I worry about Barzal. They had a graphic on the broadcast (Sportsnet) comparing either possession time or zone-entries, Barzal & McDavid, but his output remains pathetic by comparison (as do most players, and not comparing to McDavid head-to-head, but given how much time of possession he has, he rarely generates high-quality scoring chances for his linemates). Seems like he's always around the outside, very smart passer and stick handler, but doesn't drive to the net, EVER.
Starting see him as a great #2 centre even though, at times, he looks like a budding 100pt centre.
Not sure about the team speed but maybe not too far off. Would be nice if Wahlstrom/Raty/Dufour could break-out like a Jason Robertson and maybe get lucky with a draft pick.
With Sorokin, you're not far away, like Carey Price in Montreal all those years. Dobson/Pulock/Pelech/Barzal/Nelson/Lee - feels like a playoff team. Elite team needs another couple of elite players for sure.
