I am probably most definitely in the minority here. But I would play Dvorak with Zegras and Michkov, at least try it at first. It gives those 2 a defensively strong 3rd, and Dvorak can take importasnt faceoffs when needed. You can take some of the pressure off Zegras from a defensive standpoint and allow him to take faceoffs depending on the situation or importance.
I’ve been advocating that move for Cates for a while now. Dvorak is the much better faceoff guy, so I’d likely leave him in the traditional center role.
