This year I’m going to be doing weekly Big 12 rankings based entirely off of efficiency margin. Efficiency margin, for those who aren’t nerds, is a team’s points per possession scored minus the teams points per possession allowed. In essence, a measure of how much better or worse a team has been compared to their competition on a per possession basis.
It’s easy (and fairly effective) to look at teams efficiency margin in conference play, and simply rank them that way. However, I wanted to go a step further, so I’ll be comparing their actual efficiency margin in each game versus their opponent’s efficiency margin, as a means of comparing how they’ve performed based on what we’ve come to expect out of the competition.
