I think Strome will end up as a free agent because Chytil is ready to supplant him as their 2C, but I'm not so sure about Copp. Larry Brooks "reporting" that those two and Vatrano will definitely be testing the market doesn't really mean anything aside from him parroting their agents ... which is a thing Brooks does every summer. They may all eventually end up on the open market, but it would surprise me if NYR lets Copp walk without making a strong offer of their own. He's a perfect fit for Gallant's systems and they can't just go back to being a 2 line team again if they're serious about contending.Julien Gauthier and Alex Georgiev want out of NYR. Gauthier 1st round Canes pick in 2016, pretty much a bust.
Also Ryan Strome and Andrew Copp will be available as free agents
The tricky bit with NY's summer is what they end up doing with Kakko. With only $10 mil and change to play with, they've got to be careful with him, and I'm pretty sure he won't be too thrilled with getting benched for a Game 7 for what seemed to be really scapegoat-ish reasons. That's going to get a little dicey, I think.
