That's a good number for Strome. A one year deal is ideal imo. I think they can come to terms on a deal prior to the case, but I wouldn't mind if it goes to the arbiter. There's no way he should get more than Zibs, and if you split something close to the difference on a one year deal, you get to see if Strome legitimately righted the ship and is living up to his draft pedigree or it it was a one year fluke. I definitely think he is a need on the team, but the question in my mind is that, if you view next year as a year to finalize the next core, then both the team and the player are better off on a one year deal.
We don't know what free agency is going to look like after this year. For Strome, if he has another great season he is a top UFA RS Center who is going to command a premium. Strome's a pro and I'm sure he gets it. If it works out, and two years is less of a fluke then one, he can still re-up if both parties feel the fit is a good one going forward.
For the Rangers you get to see how you internal options develop, and perhaps make an upgrade if needed. Realistically speaking, with the cap the way it is, alongside the Rangers' situation, next off-season is when you can start to make moves towards cracking the window open. The team is too young to the point where making the playoffs would be a win. Usually teams this young and inexperienced are lottery bound.
