I don't see WSH parting with Neivurth even if they do retool. Grub's isnt ready for full time work on a contender imo. So I don't see them swinging a deal with Vegas to give him up.
As for Colorado, if Pickard is traded / protected, I would go with Grigorenko. Think theres some untapped potential left there and he could be a middle 6 center / winger.
Gelinas is midly enticing, but on the path to bust territory. He would be my 4th choice at best.
All year it seemed like COL might try to get Beauchemin to waiver or buy him out, but realistically what's the point? Their 5th best and beyond forwards are so terrible, if they still feel Beachemin can contribute he is worth more than them. With this in mind, players like Grigorenko might be exposed. Maybe they protect Neito as their 4th guy if they end up going 4-4 as a result of Beauchemin's NMC.
Not counting Pickard, Grigorenko has the highest upside among anybody COL might have exposed. Still, even then the guy is 23 and probably won't ever put it together. If Pickard isn't on the table, outside of gambling on Grigrenko the best LV could hope for from COL would in most cases be getting a depth player.
Comeau is probably the best pick Vegas can make from Colorado in terms of who can contribute now. He's paid fair value for a third liner but is a bit of a commitment with a 2.4M cap hit.
I can't see COL protecting Soderberg. No way Vegas wastes nearly 5M in cap space on him, especially now that we know Vegas is trying to strategically gain assets or taking bad contracts. At the same time, if they are thin down the middle it's hard to imagine Soderberg wouldn't bounce back with a change of scenery. I wouldn't take him, but I understand he shouldn't be anywhere near as bad as he was this season for COL.
Wiercioch is a darkhorse. He's never quite put it together in Ottawa but showed glimmers of being a decent player. Given the garbage heap that COL has available, if Pickard isn't on the table, Wiercioch wouldn't be a bad pick.
