As an Islander fan, trading for top-4 LHD is the #1 priority before the draft/at free agency. There's little doubt that NYI will target Chychrun, or others of that type - Cam Fowler (probably not available), Nate Schmidt, maybe? Maybe a return of Nick Leddy? Idk, but someone who can move to play with Noah Dobson or Ryan Pulock to make the breakout more dynamic. They also need a 3rd pairing LD. With Pelech, Dobson, and Pulock, NYI need to make their D unit the driving force of the team. They can imo.
The second priority before the draft is to move Josh Bailey.
Trying to add a dynamic winger should imo wait until the UFA period, as there will be a lot on the market, and a lot of parts that may move as a result. Trading Barzal for Laine is poor asset management. And there's not much reason to think that Laine would even fit the team!
Jenners leadership is redundant for NYI, or maybe it gets in the way (not a criticism of Jenner). NYI have Lee, JPG, Nelson, Pelech, etc. It's simply not what NYI are missing. I agree with those saying there's no point including him in a deal.
