The math on Seth Jones is fine if anywhere from 1.5 to 3.5 is retained. Any player traded is off the books so that's another 1 million minimum (Stanley ). If Pionk doesn't sign, our RD is still strong. With the cap going up, and any retention, it's perfectly palatable.
He's a solid top 4 RD, who was great with Zach W in Columbus, who is similar to Morrissey. His size and skill complement Morrissey.
DeMelo bolsters out bottom pair and I'm case of injury we are that much deeper. A Fluery DeMelo bottom pair is solid. That's would be a deep D.
Adding a playoff warrior forward would be icing on the cake.
Be mindful Jones has been playing on AHL.caliber teams and goalies for a while. He would shine here.
