I'm not sure, I actually think the one upside to Royal's not great offensive instincts is he's constantly looking for Kulu, if he has any set of options and pass to Kulu is one, he'll pick that. Something I don't think Doherty did enough (not picking on him, but Royal also makes himself available, finds space more than any of our other WBs). The new fit inside (and leave Kulu wide) is also an interesting ploy tactically (again, unlike Doherty he's not looking to cut inside to shoot, he's just making better use of space)
