There are a lot of different numbers, phrases, rankings, and terminology you’ll hear in bracket conversations. Two ranking systems you should expect to hear a lot about are the NET rankings and KenPom. At the time of writing, Michigan State is 47th in the NET rankings and 44th in KenPom. KenPom is a predictive system that operates off of data, with an emphasis on adjusted efficiency (both offensive and defensive) and other advanced analytics. The NET rankings are done by the NCAA and are a combination of both data and game results.
