Watch them sign Butcher to a 1 year deal, then retain on the deal and flip him to Vegas for Gusev and sign Gardiner.
I'm not sure how I would feel about that.
Frankly, I think Butcher is too much for Gusev. Everyone is infatuated with him, I get that, but he's also a completely unproven entity you're likely only going to have for 2 years before needing a new constract, and he's going to cost 4 million. Butcher + retained salary is too much. Reports were that offers were a second + low level prospect. That's like finding a house you love for 300K, knowing there are a couple offers out there at 303K, and then deciding to offer 350K. No real reason to go that above and beyond the existing offers in my opinion.
I have kicked around ideas like this (Trading Butcher for top 6 help, signing Gardiner), but but it's a risky play. Any Gardiner deal is likely short term (1-2 years at this point, I would think). That is going to leave us in a scary position on the left side of the defense moving forward without a ton of cap space (depending on extensions for Bratt, Mac, Nico, Hall, etc). Greene is a FA, Mueller is a FA and a bottom pairing / 7th D. Vats is a free agent. Gardiner would be gone likely in a year or two.
So if I'm moving Butcher for top 6 help, it's a package for something like Nylander or Ehlers (and don't jump on me Toronto / Winnipeg fans, this is just an example), not Gusev.
