I'd rather see the Rangers go with the three RD they used last year again next year, it works to the point two of them put up outstanding offensive stats.
Instead of trading for a long term center now, let them see what Chytil does at center for another year. If that means signing Strome to a one year deal for support, or getting some stopgap one year center somehow else, I'd prefer that.
All the same I think you are correct the Rangers here will rush to get a long term center, that ends up blocking Chytil or anyone else from taking that spot. The D offensively take a hit and then they end up wondering why they are scoring less as a team while only playing slightly better defensively.
I think they are a year ahead of themselves where they are envisioning Kakko, Lafreniere, possibly Miller too as being able to play a competent NHL two way game.
