This list could go in for a while. I’d like to see a Murphy (Chi) or Larsson(Sea) myself along with a Tanev trade. Two RD’s so everyone can play their own side.
Rielly. Larsson/Murphy
Brodie Tanev
McCabe Timmins
Larsson/Gio

I'm pretty big on Larsson. Murphy not as much but I can see why some want him.

I like Larsson too but think I’d prefer Murphy. It’s unfortunate he has played in bad teams most of his career and it affects his stats. But good skater that moves the puck well, very physical and a real asshole in front of the net(which I love)

Good point about Murphy, we definitely need more net front presences. I'm not opposed to Treliving going for Murphy, I think it just depends on what CHI wants back.

1.Tanev does seem to have the physical play. Can he clear the front of the net?
2. Is peeke even a NHL d-man he can't make Columbus lineup? PASS
3.Carrier another undersized no physical play d-man. PASS
4.Ferraro can block shots. Can he actually play because SJ doesn't have many options? PASS
5.Sanhiem great size no physical play. PASS
6.Borgen hits solid +/-. 2nd/3rd pairing guy. Lilly trade for him. Who adds?
7. ZADOROV 3rd pairing d-man NASTY GUY. YEEEEEEEEEESSSS
8.Lyubuskin hits clears the net. excellent 3rd pairing guy. YES
9.Jeremy Lauzon very physical guy. 2nd/3rd pairing YES

Peeke should be extremely cheap to acquire, one mid or a pair of late picks should be fine. He just doesn't have a spot in Columbus because he's redundant with Gudbranson (who's going to play because intangibles and also contract), been outplayed by Jiricek forcing his way onto the roster, and he and Werenski are a poor match (so either Severson or Boqvist when healthy get that spot because they do work with Z). He's a fit for a team that needs a big 3RD, but even Columbus doesn't need that right now-- Columbus's problems are pretty much all the forwards, not the defensemen.

I'm not a Leafs fan, but IMO getting one of Ferraro(young d-man, can block shots, comes with term), Fabbro(young d-man, great defensive play, offense is questionable, cost is a 2nd+), Carrier(solid two-way d-man, plays well physically, cost is a 2nd with half retention), Lauzon(plays better physically, comes with term), Tanev(veteran who can play 24 minutes/night, great shutdown d-man) or Zadorov(good size, physical, responsible, cheaper than Tanev) would be a wise add.
