Kakko needs to be on the top line.
This is a no brainer decision and see no reason why he isn't playing top wing over Kreider
From my POV, Kakko and Kravy are better fits with Ziba — and Laf with Panarin and Strome — than vice versa.
Kreider can be a good fit with Ziba too, especially if “new” Kreider mix it up more. I am all for spreading out the talent, ultimately I wouldn’t be surprised if we ended up with a bit different structure than we have seen in the top 9.
It won’t get a ton of love, but I would actually like to see something like:
Kravy-Ziba-Kakko
Panarin-Laf-Strome
Kreider-Chytil-Goodrow
Blais-Rooney-Reeves
