Pac-12 Basketball: Individual Efficiency Margin

How much value does each player contribute to his respective team in terms of efficiency?

NCAA Basketball: Washington State at Arizona Casey Sapio-USA TODAY Sports

A few months ago I published an article laying out the basis for a statistic I had created, called Individual Efficiency Margin. Its purpose is to determine how much value each player brings to his respective team, based on offensive and defensive efficiency ratings.

As an example, a tremendous player on a relatively bad team (i.e. Washington State’s Josh Hawkinson) will have a significantly higher IEM than an average player on a great team. Players that aren’t efficient that play on fantastic teams (i.e. UCLA’s Isaac Hamilton) will almost always rank near the bottom of the conference. For those who are confused as to why certain players are ranked higher/lower than expected, this stat is once again team-specific and differentiates how much value each player brings to his respective team compared to his teammates.

The ratings are then weighted on how many minutes the player records, so I do not have to weigh players that appeared for just a handful of minutes this season and had absurd ratings.

With the help of Sports Reference and KenPom, I was able to create a table outlining each qualified Pac-12 player and where he ranks among his competitors.

  • Off Rtg - points scored per offensive possession
  • Def Rtg - points allowed per defensive possession
  • Min % - percentage of available minutes recorded
  • Plus/Minus - IEM, overall team-specific efficiency value added to team
