One guy I wouldn't mind picking up is Nicolas Hague from the Golden Knights.
They (the Knights) have almost zero cap space, and Hague is due for a raise. I don't know what kind of maneuvering would be needed to make the deal happen, but adding a physical 23 year old 6'6, 220 lb defenseman would be a solid pickup,
Maybe something around Paul Byron (more LTIR space for Vegas), a prospect like Riley Kidney and their 4th round pick back in 2023? Would give us some nice depth on the left side, and would give Guhle time for a years seasoning in the AHL, before they move Edmundson (in a year's time). Basically Hague would be Edmundson's replacement.
2023 Lineup looks like:
Caufield - Suzuki - Anderson
Hoffman - Dach - Dadonov
Pitlick - Dvorak - Gallagher
Pezzetta - Evans - Armia
Matheson - Savard
Edmunson - Barron
Hague - Harris/Wideman
