I'm not sold on the theory. Sure we have a winger, potentially two, ready to come up and stay up (Lee and Ward) but beyond that there isn't a whole lot going on in Ontario which would be an upgrade from Kuz (or even equivalent). Greentree is really the only other potential right now, and Ward is, in all honesty, still borderline. Additionally, I like Malott but I'm not sure he really should be considered a full-time NHL player.
Then we know Perry and Kopi will be gone next season, creating two spots.
Really why would we move one of our players who is strong on the PP (which our team is weak on), plays a solid two-way game, and has offensive zone talent? I was all for not resigning Kuz last season, but he has changed my mind this season. He works hard, demonstrates a high hockey IQ and appears to have fully bought into Hiller's mind-numbing system.
I'd rather see Moore or even Foegele moved if space is needed. I would rank Moore higher than Kuz, but he also has a lot more trade value. Foegele seems like a player built for the playoffs, and while we need players like him his offensive struggles this team really hurts on a team like the Kings who struggle to score goals.
