I disagree that is a very bad metric. I think it is a very good metric. Because you say so doesnt make it so.
You and I have gone through this. Over the past 3 seasons, Makar and Fox both have received more defensive zone draws without their top line forwards, where Hughes was specifically given more O zone faceoff starts with the lower lines.
I get it, you like to look at blanket stats without context, but here it is again for you. Its easy to look at 3 top dmen who all play PP time and the bulk of minutes 5v5. Looking a little deeper is where the meat is.
This is out of the dmen's control, but also add in FO%'s over the past 3 seasons. Adds a little more context to potential opportunitiea each dman gets.
