The problem of course is that a low-ceiling but more consistent player does little to help the team win a Cup when they need an elite level performance out of their 1C to allow them to win.
You need strength up the middle to win. You don't need two 1Cs to win. We've got some center talent in the pipeline. What we
need right now is another solid top-6 center and a goalie.
So first of all, Kuznetsov is already a solid top-6 center. So we could stand pat at the position and be fine except for our cap problems. I just wanted to mention this up front. We don't absolutely have to part with Kuzy unless we end up needing the money and can get a serviceable replacement for him.
Another option would be to look at someone like Danault. Comparing him to Kuznetsov would be silly. They're so different it's almost like they're not playing the same sport. However, what we lose offensively we gain elsewhere. He's an elite PKer, solid defensively, and very good at the dot (lefty). He's Eller, only 4 years younger and strong on faceoffs.
We can swap Danault and Eller or their wings to find the right chemistry and matchups, and with 2 years left on Eller's deal that takes him to age 34, he's an Eller replacement if CMM emerges the way we want him to. A good investment when viewed that way, but it banks on CMM panning out while he's still got cheap years.
Or we can rent a Krejci for a year or two as a stopgap. Rentals aren't very ambitious moves, but they're low on risk.
Neither idea is sexy, but nabbing a guy in free agency would allow us to move Kuznetsov either for futures or maybe a talented young goalie -- far easier (and more realistic) than trying to package him or move him for something loftier in a buyer's market.
Yeah, if there's a blockbuster to be had that won't bust our block in the process, go for it. But that's wildly unlikely with how little we have to give. So if they feel they must move on from Kuznetsov, I'd be okay with moves like these that keep us strong at the position.
