It all depends on the return, though. If it's trading to make room for kids coming in, Guhle isn't going anywhere. If it's trading to get a high-end forward, he's the one who should be able to return one, it's just a question of whether a good enough one can be obtained.
To put it otherwise, Montreal will need to trade D, and it could take the form of
-Guhle and Winnipeg's first for Zegras (or Necas, or some other 60+ point forward)
OR
Harris for a 3d.
I'm aim for a guy like Newhook was a year ago (Tomasino was mentioned elsewhere) for assets other than Guhle or Montreal's 1st, but that's just me.
