If I ran the team, this is roughly what I'd try to do for next year:
Forwards
??? - Spezza - Hemsky
MacArthur - Turris - Stone
Hoffman - Zibanejad - Ryan
Greening - Smith - Condra
Puempel, Pageau
Puempel shoots left, Pageau shoots right and can play centre, so between those two you're covered for any injuries/extended suckage among forwards.
Waive/trade Neil, waive Kassian.
Unless they can do another MacArthur type signing of some undervalued guy coming from a team whose coach hated him for no reason, I'd like a board warrior who's a good stick checker for Spezza's LW.
Defence
Methot - Karlsson
Wiercioch - Ceci
Claesson - Gryba
Chris Wideman
Depending on how Claesson looks, you could put Wideman in there for some extra puck movement on the 3rd pairing. Wideman also is also insurance for Ceci slumping or regressing somehow.
I'd also be fine with signing a good UFA D-man to replace any of those bottom 3 guys, with emphasis on him being good. No one over 32, and not a pylon like Komisarek or something.
Waive Phillips, trade Cowen.
