To me, it all depends on how the Kings do this playoffs. If they get eliminated early or win the cup, trade everyone.... cause who cares, you choked or you won the cup.
But if they go deep, they should keep Arvy for one last shot with Kopi (unless you've got some team willing to overpay for Viktor), and shed as many of Iafallo/Moore/Walker/Durzi/Peterson to re-up Korpisalo/Gavrikov/Vilardi. I think 33's production is worth more for another deep run with Kopi (assuming he doesn't fall off a cliff) than whatever fair return Kings could get.
The year after, who knows what's gonna happen....Kopi could retire, he could commit to 1 or more years, he might fall off after Blake drops another Peterson-like extension, etc....in addition to the other expiring contracts: Lizotte, Grundstrom, Byfield, Kaliyev, Roy, Walker (if he's around), Durzi (if he's around), Spence, and Copley.
