I think Columbus is willing to trade just about anything to make it happen and has the cap space to relieve teams in a bind.
It also seems unusual that people say there’s no way it could possibly happen, while there seems to be availability for players like Hertl, Couture, Miller, Horvat, Monahan, Kuznetsov, Kotkaniemi, Johansen, Duchene, Danault, Nugent Hopkins.
I don’t think all of those fit the bill as clear cut 1Cs, but there’s certainly some centers that seem like they’ll be available this off-season.
Columbus could offer: cap space, four 1sts over next two years, Domi, Nyquist, Bjorkstrand, Gavrikov, Jenner, even Roslovic or Laine. top U-21 players Foudy, Texier, Bemstrom, Marchenko, Voronkov, Chinkhov.
There are plenty of options.
Edit: I failed to mention Korpi/Elvis, for any cap-strapped team that needs a starter for next year at $4M or $2.8M.
