Well, I would counter his is kind of a luxury as he is a player you have to "indulge" their limitations. Hell, Lukaku was essentially the same thing. Lukaku scored goals but offered nothign else. James is simply just not going to be a defensive forward and I have no desire, at all, to want him to be.
It's the jobs of Doucoure, Allan and Carlo to mitigate the "issues" that James not tracking back as often creates.
This is sounding so much like a criticism of James and it's not meant to be at all btw. Just having a brain fart of how to phrase it.
