He actually hasn't made a lot of brilliant trades (Sakic is much better), has used cap room to pick up talent on the cheap.
He cleared out the players Brind'Amour didn't want and freed up cap room, but didn't get a lot for them.
As far as your last sentence, I might agree with that if the grading scale ended at zero. Sadly, as we've seen from situations like JVR, they don't. Avoiding paying for dumps is a strong positive on multiple axes.
I have some time today, so let's do this.
6/23/18: Hanifin and Lindholm for Hamilton (left after 2 seasons), Ferland and Fox (flipped 4/30/19 for 2019 2nd, 2020 3rd)
They traded two solid player for two undeniable stars and a solid player. Of course, Fox was cheap because he would only sign with NYR, but they took a stab at a star with depressed value and still got value out of him on the other side. A++ by any definition.
8/2/18 Skinner for 2019 2nd, 2020 3rd
They determined that they didn't want to sign Skinner to the UFA inflation rate deal and got value for him. Excellent process.
1/17/19 Rask for Niederreiter
They got the clearly better player from a team that chose fit over talent and determined they were making a shake-up trade at all costs. Excellent process.
6/22/19 6th for Marleau, 2020 1st [salary dump by Toronto]
They rolled over their Skinner decision and leveraged it to its fullest. Excellent process.
6/24/19 DeHaan for Forsling and Forsberg
They got out of the De Haan contract after he destroyed his shoulder and didn't take ANY salary back. Took a buy-low chance on a post-hype prospect and a Goalie who ended up not only sticking in the NHL, but getting paid. Once again excellent.
I didn't like this one at the time because I was high on Roy. But he wasn't a likely star or anything and they only gave up a 5th to get an average Forward. Let's call this one aggressively fine even if I wouldn't have made it.
6/30/19 Darling & 6th for Reimer
For the cost of a 6th rounder, they clearly upgraded the roster spot and saved 750k in cap space without adding term. And the guy they moved out had a modified NTC.
2/24/20 2020 1st for Skjei
Deadline overpay for sure. Also turned into a really good player the last ~1.5 years. Call this whatever you want and I won't argue.
2/24/20 Luostarinen, Wallmark, Haula for Trocheck
Not only clearly got the best player, they walked away when he hit UFA at 29 instead of turning the move into a mistake. Excellent once again.
9/12/20 Edmundson for 5th
This was the COVID timeline change. They managed to get the Canadiens to give them a draft pick for a player who was already a UFA. Only poorly-run (Hi, Chuck) teams buy free agents. Excellent yet again.
4/21/21 Fleury for Hakanpaa (TDL rental)
They also got a 6th back in this, which was the asset I'd most like to have. Fleury has always sucked and I've always killed them for drafting him. But they're the ones that got a pick. This is a minor win.
7/22/21 Nedeljkovic for Bernier, 2021 3rd
They determined that they weren't going to pay Nedeljkovic what he wanted, so they got a good pick out of it and took zero salary back. Yet another win.
7/23/21 Bean for 2021 2nd
They got a top 50 pick for a guy they didn't want to pay, right at the end of his ELC so his value was still high. Love it.
They moved a depth piece who was topped out developmentally for a guy who might have been more than that based on the info we had from Edmonton. Then when he wasn't, they got out quickly and got a pick back. Good process here once again.
3/21/22 Hreschuk for Domi and Inamoto
They bought a post-hype useful Forward with full retention and no term for the price of a 6th rounder. Not exactly great, but a perfectly reasonable depth move. And then they didn't pay him. Looks good to me.
7/8/22 TDA for 2022 4th, 2023 3rd, 2024 2nd
An absolute master class in asset management I have no desire to enumerate again.
7/13/22 Lorentz & 3rd for Burns
*Burns with retention, which is why the trade made sense.
7/13/22 Pacioretty for "future considerations"
Personally, I enjoy getting good players for free.
______________________________________________________________________
You listed out all of those trades and the worst one I can find is aggressively fine. But they always make sense.
You also forgot the one big mistake you could argue they made, but Faulk is so high variance that I never feel like I have a good handle on what I think of him as a player.
