Justin Barron could fit that spot.
MTL : Barron
for
Utha : Lamoureux
I'd be pretty surprised to see Lamoureux moved for anything shy of a top4 D/top 6 F (not 1 for 1, but he's a big boy and moves the puck real well).
Lindgren is super interesting. Utah would likely only get ~75% of a season out of him based on his injury history, but he's a legit player. I'd do a 2nd and a prospect, I don't think a 2nd alone is enough for a 2/3 defenseman who's all of 26.
Graves is also interesting, I'd probably do a 3rd or 4th + prospect.
If there was a team who could offer a bigger, two way style 1/2 center and 2/3 defenseman, I'd open up my trade chips pretty heavily, especially if they're 27 or younger. It's early and I haven't been watching the games, but Hayton seems to have found his stride based on the stats and what I've read. Maybe I'm being premature on the top 6 center thing, but I've been of the opinion that an additional top 4 LD would put us into bubble territory.
