It's normally safer to keep the pick. What players are on the table that could make an instant and long-term impact?
Peterka would be an impact player and a cheaper option over Marner, but the Sabres (Anaheim of the East) don't want more picks and are in the same situation as us. Minny wouldn't trade Rossi for a pick either.
Maybe Ramus Andersson if Calgary can't extend him, and if they planned to go after UFA defensemen? But is he worth it with one year remaining if we can't extend him?
Devils noted that they will make some big changes. Maybe we can obtain RH Mercer or RHD Nemec but would need to either eat a bad contract like Palat, or package a good prospect to include riskier contracts in Meier or Hamilton. Meier would give us a power forward and Hamilton could help our PP though. A Mercer/Hamilton would probably cost us quite a bit unless they just want to unload Hamilton's contract.
Lightning might want cap flexibility and cheap young contracts in return too. Isaac Howard + Cernak/Cirelli/Paul? Would probably need the 1st + someone like Zellweger in return.
