Being Jewish, I'm very biased in NYI having their very own Jewish star player, when both the Rangers, and Devils have one. (Chychrun is also, like me, a Cashew - having one Catholic parent.)
But it makes no sense. So much of his value would be on the PP anyway. Are you going to move Barzal off the PP1 for Chychrun & play 2 D? Or move Dobson off the PP1?
I agree with Leaponover that the best way to improve NYI is to improve defensively. However, I feel pretty certain that the best way for NYI to do that is to improve the forwards. NYI's problem isn't (for the most part) defending, it's winning the race to the loose pucks on the defensive half wall, getting possession, and making good first touches. They need a Jamie Langenbrunner type.
