@SethPartnow @GreekGodofStats I mean it probably depends on whether the denominator is a +/- system where defense is assumed to be equal to the sum of its parts, or one where interaction effects and coaches/schemes are accounted for. For the time being, I'm just focused on better publicly-available +/- stats. — PolitiTweet.org
