However, what you say about the DPR is also true of the OPR: it is a function of both the offensive output of the alliance AND the defensive ability of the opposing alliances. As you point out in your (impressive) paper, these scores are mostly impacted by the offense (except in Stack Attack ) with a small impact by defense on both sides. It's the deviation from the expected opposing OPR created the presence of a particular team that measures the defensive impact.
