I'll spell it out for you because clearly you're a Homer fan and have a lack of understanding yourself and just want to criticize someone else for having an opinion:
The Jets Need:
-Cap space (this year and next for Morrisey, Trouba, Helley, Connor, Laine, Wheeler, Lowry etc.) This year we need if for key RFAs as well as Bonus covereage to not suffer an overage next year when we need it most.
-A defense that defends well (Myers isn't that. He puts up points but he's not good defensively and I'd love to hear your argument that he does!) We've got goal scoring forwards in spades and more coming, we need our D-Core to focus on keeping the puck out of the net and quick puck movement out of the zone
-Assets to keep the train rolling (ELCs will becoming increasingly importent the next 3-5 years to extend the window while all the current guys get PAID)
I could write you a list 10 pages long but those are the specifics relating to my initial opinion. I've done the math many times and played with the salary cap rigorously and though Myers wouldn't be my first choice to be moved (Kulikov, Chiarot, heck even Perrault), but he's the logical choice because A) Poolman can play the 3rd pairing minutes B) He would actually garner assets not COST assets (Kulikov, Chiarot) C) His value is highly inflated due to scoring numbers and counting stats which hide his underlying numbers for some D) RHD are the most coveted item in the NHL right now E) You can't spend 11M on a third pairing defense.
