I'd be happy to see Grier move on from Kostin. I feel like he had this year to sort of show if he deserves a place on the team going forward and, safe to say, he didn't take that chance. And to the point of his mental game not being there, it's kind of a shame because with the tools he's got, you could find a place for him in the bottom six, but when we're stuck with a guy like Goodrow and committed to younger guys like Ostapchuk, where does he fit in? And he's sort of a liability in the vein of Kunin, only to a worse degree. So, okay, that's enough of that.
Kovalenko, on the other hand, feels to me more worth another year--I guess I see him sort of where Kostin was a year ago. Injuries have certainly affected his performance after that positive start. I'm not sure if he will make it in the NHL, but he's got the kind of spunk to be a contributor in the bottom six, maybe as a plug-and-play guy in the middle six if he can develop more consistency (which could come with better health and thus more consistent playing time in which to steady the ship). That said, it wouldn't surprise me if he decided to just go back to the KHL.
