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.
Parise will be the biggest loss of that group. He was more impactful than Trenin. The day 1 forward group just doesn't look all that strong:
Drouin-Mack-Rants
Wood-Mitts-LOC
Kovalenko-Colton-Kivi
Kelly-Wager-Polin
That's a bottom 10 forward group. Top line... Mitts and a bunch of flawed bottom 6ers. Now if one (or both) of Lehky or Landy are ready to go that certainly helps a lot. But that doesn't elevate a ton, it just gets the 2nd line up to snuff. Until Nuke comes back and if health persists, the forward group will be a weakness and reliant on the top line carrying things.
The team as a whole for the first 10-15 is a weak forward group, bad goaltending, and a good (but soft) defense. Luckily in the regular season, you can get away with a soft defense and a good defense raises the floor. What it will take to start hot is George being good and the top line to take over games and play 22-24 minutes. If anything falters there... getting to Nuke and Lehky's return might be about holding to .550 hockey.
Vegas was proactive in replacing their departures during the season... Martinez to Hanifin. Stephenson to Hertl. Both of those are sizable upgrades. The one they didn't do that with was Marchy. Where I don't think Holtz is the guy that replaces him but Brisson is. Holtz is more insurance. Their forward group looks like:
Barbashev-Eichel-Brisson
Dorofeyev-Hertl-Stone
Olofsson-Karlsson-Holtz
Howden-Roy-Kolesar
Their defense projects as:
Hanifin-Pietrangelo
McNabb-Theodore
Hauge-Whitecloud
They are really strong down the middle. Eichel and Hertl are both 1C capable guys. Hertl is more of a question on age, injuries and regression. Karlsson is still a very good 3C and Roy would be a 3C on most teams. Where Vegas is weaker is on wing. They are talented but flawed. I hate Olofsson as a player and I think that will blow up in their faces. Brisson is a gem though and should step in as a 2nd line quality player. Doro showed NHL ability needs NHL consistency. Stone and Barbie are good top 6 players and fit Vegas like glove. The defense is still strong, need to not regress.
All that said, Vegas is just a playoff team as they sit. Night 1, their roster looks way better because of their advantage at forward. There isn't enough though. When they eventually pull off the Theodore/Marner trade... that's when they could elevate back up.
