Love it - hate it - ignore it, but I for one like the idea of ESPN's Real Plus/Minus (RPM). Traditional Plus/Minus does not take into account a specific player's teammates and their offensive production and defensive contributions - whereas RPM does that. If a player is on the court with a bunch of duds, his traditional Plus/Minus will suffer. Put that same player with superstars, and his traditional PM will soar. Real Plus/Minus allegedly alleviates that defect.
The first four spots in front of Kyrie are occupied by James Harden, Anthony Davis, Paul George and Nikola Jokic, in that order.
