You don't put Miro on the top line when his production has been minimal playing on lower lines. I think you go back to the lines when OV was still healthy and just plug-in for him.
Lower lines being asked to do what?
There are
maybe two other guys on the team who could make the move he made the other night and create a real scoring chance out of being marked. Give him some minutes and freedom to try doing that,
vocally change his mentality and role from "don't give anything up" to "go make something happen" and see what you get.
At the end of the day Raddysh also has minimal production on lower lines, so it's not really like this decision would rob a deserving player either. Ovechkin isn't a defensive lynch pin, I'm pretty sure they can handle a guy contributing about as much defensively while trying to create, so give that role to a creative player.
