Why though?

1 for 1?
; )

It would never happen, but it's crazy to think they actually have similar value now

Not really. Both got worse but Hall is still a top6 forward while Larsson had a bad season last year and is a #4-5 D. We'll see what happens this season.

I haven't seen much of Larsson lately tbh. But I've seen several ACGM teams where other teams want to acquire him for a 1st rounder so I assumed he was playing well. He's averaging 23.5 minutes a night as Seattles number 1 defenseman. For a team that's in a playoff spot that's hovering around the 10th best defense in the league, I'd say Seattle and other GMs must find him decently valuable. Especially because none of the Seattle goalies have been making their dmen look good, lol.

Maybe not as valuable as Hall, but I don't think it's fair to call Seattles most utilized defenseman a #4-5 D

Just because you're used as a top pair D doesn't necessarily mean you're one especially on bad teams (see Columbus, Montreal, Arizona's top4). He's had a good start this year but there's still a sizeable gap between him and Hall.

what a league altering trade
