One player who might be earning a professional tryout (PTO) deal somewhere in the NHL is Klim Kostin, who supposedly has had conversations with the Kings at this point. In a recent interview, Kostin confirmed his interest in joining the Edmonton Oilers again, considering how well he fit with them in his previous stint, but confirmed the Kings have reached out to him. The way he worded it made it sound like they had made an offer, but that's not confirmed just yet.
The Kings signed six players on Day 1 of free agency, focusing on filling their critical roster holes, but did not secure a top-tier forward or defenseman.
