A year is not enough. It's somethiong you have to revisit in 5 years. Let's just pretend Kova has a breakout season. We have seen this movie so many times. He's 27. He'll have 2-3 good seasons and then hit a wall at 28-29. See Paul Byron, Oleg Petropv, Brent Clark, ... the narative that we could exploit that to get a pick at a deadline is flawed cause it would line up with us starting to compete and then KH would have the useless pressure to keep Kova.
We have so many young dmen with potential as high or higher then Kova. Struble, Guhle, Mailloux, Hutson, Engstrom, Reinbacher, Kony, Xhekaj, Barron, i'd even be temped to add Protz but that's too soon. They don't all play the same style as Kova but they all got the potential to be in front of him in the depth chart. Some of them will flop obviously but that's 9 names who will need TOI very soon. Keeping Kova just to upgrade a 4th into a 3rd would have been a waste of his and our time. KOva will need to be the next Souray for this trade to stink.
And before some people start to ramble about how Barron sucks when Kova was the same age as Barron he was playing in the AHL and was a middling prospect. Winnipeg waived him two years later without giving him a proper chance. Dmen are not a finished product at 22.
I'd rather no waste time on a 27 years old "prospect" who will be on the decline once our rebuild is done and who was not any better than Barron when he was the same age.
