If your point is that he is not healthy and needs to take a rest...that is the furthest thing from a healthy scratch that you can have. That means he is sitting because he is injured. Kane has been skating very well over this road trip and has begun to create scoring chances again. I think his ankle is good to go. If you want to sit him because he is injured, then that isn't called a healthy scratch.
Point well taken, but it is contributing to his lack of play. My only suggestion is give him a night off that is close to a little bit of a break to get his head and ankle back in shape. Remember, he's only 20 and we are looking at the playoffs this year so we need to give him rest when we can.
