All I said was Walker struggled, he's a good player for sure, and signed a sweetheart deal.
Duhaime, Parise, and Trenin will essentially be replaced by Kelly, O'Connor, and sadly Wagner. The big sore thumb is Wagner <-> Trenin, which is a massive downgrade, but one I don't think is going to kill Colorado against the average regular season opponent. Trenin didn't fit in well with the team, but was still rock solid defensively. Duhaime on the other hand I don't even see as a loss. For as good as he was in the regular season, in the playoffs he and his 7 minutes of ice time was an idioctic penalty waiting to happen.
The caliber of player Vegas lost relative to the Avalanche is so different it's not even comparable. Marchessault and Stephenson were franchise pillars, and they also lost some good depth players. It could all work out, Holtz could pop off, Olofsson could re-bound, etc. But at face value what went out was a lot better than what came in. And for all the talk on this board about age curve, a ton of the best Golden Knights players are already on the wrong side of 30.
