Josh Bailey says hello. Andrew Ladd, too. If Lou wants/needs a player gone, he'll pay the price to make it happen. With that in mind, it's a near certainty that at least one of the 4 vets with contracts that expire over the next two seasons get moved now, prior to free agency, and probably at the draft. We got that extra pick for a reason, and it's not to make a selection.
Nelson, on the other hand, could probably be moved without a sweetener. But unlike some (many?) Islander fans, I saw some clear signs of decline in his play this year and his days as a center are probably numbered (we did try him on wing ourselves this year, to awful results, unfortunately). I expect that pro scouts noted the same, so the return won't be very high if Lou does decide to move him. That's okay, as right now, I think his cap space is more valuable than he is. Ditto for Palms by the way, who is very unlikely to repeat what he did this season. As the old saw goes, it's better to move a player a year too early than a year too late, and if (yeah, I know, big if) we are going to do anything significant this off season, getting more cap space is a must.
