you get significantly worse here

Avs accept

in what way? ...which trades are that bad in your opinion?

sorry. i should have been more polite. in my OPINION - i think all of these trades hurt the Penguins THIS year specifically - except the Kraken trade (you get a good defenceman but losing X=Zucker and replacing him with MoJo hurts your forward corps IMO)
i think the Pens really hurt in the Nashville trade. kapanen is far and away a bigger contributor than tolvanen will be

Detroit takes that for sure but idk why Pittsburgh would

Even if Tolvanen tops out as just a Kapanen level contributor, age and cap hit make Tolvy the significantly more valuable asset. NSH doesn't consider this.

I wouldnt accept that, ZAR is a pending UFA, and Maltsev has shown he has a lot of talent and can be part of the avs depth long term.

ZAR is one of the best defensive forwards in the league. Maltsev has been good in the AHL but his NHL showing was kinda bad. Hes easily replaceable and ZAR gives them a better chance to win now

Nothing against ZAR, just dont trade Maltsev for him., he was bad a few games ealier on, but everytime he has been in the lineup since he has look solid and doing what he needs to do to be the 4C starting next year

give up a draft pick for ZAR, not a useful prospect like Matlsev

fair enough - if we could get him for picks then thats ideal but if not I would still be willing to move Maltsev for him if needed

Red Wings accept

Wings aren't paying a good asset for Pettersson, he's borderline replacement level, dime a dozen D they can find in UFA. If Pens want to pay to unload him or give him away at a bargain then maybe

I also wouldn't move Maltsev for him but would do a draft pick.

Colorado, Detroit, and Seattle
Aston-Reese for Maltsev, 5th: Reese is a 4th liner that EVERY playoff team wants. Maltsev is not an NHLer.
Pettersson, DeSmith for Greiss, 2nd: Greiss is not an improvement over DeSmith, considering contract DeSmith > Greiss. Petterson > 2nd
Zucker, Hallander, 2nd for Johansson, Soucy: Zucker > Johansson one the ice, 2nd > Soucy. I guess the positive value for the Pens would be $2.75M cap savings next year.

Go overall by position
DeSmith > Greiss
Pettersson >> Soucy
Aston-Reese, Zucker, Hallander >> Maltsev, Johansson
nothing < 5th
2nd's offset (literally same 2nd)

Considerably bad value for the Penguins. If they want to open cap space (moving Zucker and Pettersson) they could do much better.

You ignoring Pittsburgh's current needs. Chemistry of the team is issue. Blueger is instrument of Pittsburgh's defensive play. ZAR is great defensive player, but his offensive side is useless, I believe Maltsev has potential, he was better with NDJ, the fit could play huge role, but even if he does not make roster I wouldn't mind to put there O'Connor or Zohorna. Greiss is playing behind significantly worse defense than DeSmith, but the key part is he has play-off experience and can help Jarry with that. I don't like Pettersson's play at all, and his contract neither. I don't trust him. We need someone harder than him, that's why I wanted Soucy. I know Johansson does not bring much, but neither Zucker and he also cousing problems for another year. I think if they could do better with Zucker and Pettersson it would've happened already.

You are ignoring that apparently both Sullivan and management (Hextall/Burke) like Zucker and Pettersson. Outside of cap space (which I commented on) I expect that they have zero desire to move either.
