The problem with assists in this metric is that this is an "efficiency" stat. For every potential positive (a point earned) there is a potential negative (a possession counted against). Counting assists is giving someone credit for something that can't have a negative. If I counted assists, it would mean that if all I did was pass but never shoot my "efficiency" would be infinitely high which wasn't the story I was trying to tell. Numbers can tell any story you want, but this one was not meant to be a goodness or badness stat. It's purely meant to show "When an individual is attempting to score, how efficient are they at doing so." In this case KC is NOT good at converting his attempts to score into points, so he should focus on helping others do so (assisting) and not be the number one consumer of possessions on the team.
