Sissons is a player who would be pretty hard to see shipped off from the Predators standpoint. He has always been consistent and does so many great things at both ends of the ice, and there is a reason that the team signed him as a bottom six player to a seven year contract.
He has been worth every penny, and a potential trade would have nothing to do with how he has and is still performing. The issue is that if the Predators are looking to sell and go in a more youth oriented direction, particularly on offense, then Sissons is not needed.
Just as is a big part of what makes Granlund expendable, the Predators have an absolute logjam at the center position. Many of their promising youngsters are naturally and best utilized as centers, and if you are needing to free up a space down the middle, then parting with Sissons makes sense.
He has three years left on his contract after this one is over, but once again, he has done nothing but play up to the level that is expected of him. If a team feels as if they need an extra piece or two to make them tougher to play against come playoff time, someone will be interested in Sissons.
He is 29 years old and with the Predators season going in an unfavorable direction, there likely will not be a better time than now to get some value for him.
