What did Calen Addison go for? A 5th round pick and contract slot dump?
So...a bit less than that, as he's even less established. Spence may be a little bit better defensively, but he's not likely to emerge as a Spurgeon-like tiny shutdown defenceman either, and doesn't necessarily appear to have the same sort of bonus powerplay upside.
It's not even like the Kings would gain anything by swapping him for a comparable value/situation Forward. Doubtful that would be a real upgrade on anything that they already have in-house, so they'd probably be buried as well.
It really just doesn't make any sense at all for the Kings to move him for what little he'd actually return. Spence might have some minimal value to Playoff teams as an extra layer of "buried depth" that can actually play NHL minutes...but that puts him in the same sphere as a world of other veteran "journeymen" types who are also buried. Which means he's probably just got far more value as "buried depth" for the Kings than anyone else.
If they decide to move him, around the draft or free agency, or even the fall in camp probably makes more sense if they don't want to play him...and know more about whether they'll still have Roy at RHD or not.
Brendan Guhle hasn't been on an NHL roster for over a year. You could get him whenever you want.
It's jest, but honestly...it's not that terribly far off in reality.
