Not close. Leafs would likely have to give up their first for Larsson. I've seen some really over the top suggestions here as well. So no big deal. But this is really lowball offer. Id Imagine this trade to look more like the Leafs send a first round pick and a D prospect like Chadwick or Kokkonen. For Larsson with 50% retention. Then the Leafs would have to add a player to make the money work. Lagesson or Gregor maybe.

I think that might be one of the most lopsided trade suggestions for Larsson I've seen, and it's not even remotely close to enough value. In the (HIGHLY unlikely) scenario where they entertain trading him, they'd be punting on the season, so Brodie has no value to them. For all the Kraken lack in high end forward talent, they have plenty of forward depth, so Gregor wouldn't even crack the Kraken's active lineup. Late round picks are late round picks. All in all, there's nothing of even decent value for Seattle in this offer, and they would reject it out of hand.

Since there's been a lot of mock trades for Larsson, I made my own post where I put together what I would consider a reasonable hypothetical offer: https://www.capfriendly.com/trade-machine/32774

I agree with you that the trade offer above is a lowball, but an offer of a first rounder and Chadwick/Kokkonen for Larsson at 50% retention wouldn't sway the Kraken either. I think a good trade comparable would be the deal Toronto made for Muzzin, where they had to give up some quality young players in addition to the first rounder.
