Quoting: End_of_the_Laine
They might, but honestly if they think they are a contender they will need a reliable goalie, they would get one year at a reasonable hit with one of the best, and easily be in a position to extend.
Clarke was unmovable for multiple years of Chychrun. No way he's moved for a rental, like at all.
The Kings will likely try to hold on to Petersen one more season to make his buyout easier (unless a better trade comes up). They have most everyone signed except Vilardi and Kupari of the forward group, so with whatever remains they need to address LD (Gavrikov or whoever they need). The Kings will likely keep Petersen and Copley next season, unless they can find a good goalie who would sign for $2-3M,
Free agents include: Samsonov, Varlamov, Bishop, Andersen, Talbot, Jarry, Nedeljkovic, Blackwood, Raanta, Korpisalo
In short Hellebuyck would just be a temporary patch even at 50% retained, there is no point in losing your best prospect for a rental. Would you trade Perfetti for a one year rental?
