I think the Rangers absolutely made the right hire with Lavy. They needed a system, structure, and accountability. Also to let the kids play. He is the right coach for all of that. The last coach was absolutely the wrong coach for that.
Truth be told, I'm not sure it will matter though. To me the team sinks or swims with Laf, Chytil, and Kakko taking pretty big steps forward. Can they/will they do it, don't know, but Lavy has to start with them in important roles and see where it goes and if they are up to it, because it is the only way this team truly can win big, especially in a stacked Met division.
Laf on line one with Kreider and Z, Chytil should be the 2nd line C (Trocheck is well suited for a 3rd line checker/gritty/win big FO's role), Kakko will be in an important spot on RW.
I am also concerned about Laf, he doesn't look good. Makes low % mistakes, doesn't shoot enough, I am concerned by him the most of the 3 - Laf, Chytil, and Kakko. At some point he needs to man up and step up. He will be given a chance this year, it appears with Kreider and Z, and he has to man up and own it. No excuses if that is the case.
