The Panarin situation will play itself out, he'll be gone by the trade DL, and for sure won't be here next season. That's $11.625M opening up. Plus Soucy's $3.25M also opens up after this season.
To me the # 1 guy they should do everything they can do to trade is Zibanejad. I'm so done with him, I think his game is a not even close to what it used to be, plus I think he is soft mentally as well. I would make every effort possible to move him.
As for Fox, I certainly wouldn't be averse to moving him, his game has also regressed big time, hard to believe this guy won the Norris a few years back, so I have no issue dealing him. With that said, if given the choice I say Zibanejad is by far the # 1 guy I'd look to move. Fox, I think can still salvage his game and get it back, Zibanejad I think is 100% cooked with regards to being a top-level player.
As for the kids, to me multiple things can be true. I'd play Othmann and Perreault, what do you have to lose, the issue is none of the kids the Rangers have will be difference makers. Maybe Perreault will be a top 6 forward, maybe, but that's it. So, play them for sure, why not, nothing to lose, but they are not making the Rangers a competitive team, we have no kid who will raise the level of this team and be a difference maker, sad but true reality.
