Palmieri

Frederic and a 1st is pretty similar to Foote and a 1st tbh.

It looks like too much but it's an expensive market

no it's not. Frederic is 22, He should be making the jump by now. He's got 2 years in the AHL now, There isn't much excuse there.
Foote is 19 and there is still hope for him to make that jump and be an impact player. While I'm not saying it's written in stone he will fair any better, there is much greater hope he will be playing in the NHL at 22.
Kuhlman is a body.
Moore is a decent add on though

I think this is close for both sides. Would make a couple changes....

1. Dial the money back a bit since he is under contract for next year.
2. Add 2022 conditional pick if Palmieri resigns or BOS wins conference.
3. Replace John Moore with Lauzon or JFK or anyone else

There's also no room for frederic to play in the nhl regularly. BOS is deep at C, hence the very few call-ups frederic has had which were due to injuries down the middle.
