Debuting in the 2018-19 campaign to replace the former RPI, the NET is a computer rating system that the NCAA tournament selection committee uses to determine the strength of tournament candidates.
It uses a complex formula to rank all 363 D1 men’s basketball programs, which is built on a team’s performance against opponents in each “Quad.” The quads are quartiles of the national rankings, with the top programs belonging to Quad 1, and lowest-ranked programs fitting into Quad 4.
It is also worth noting that the NET does not factor in matchups against non-DI opponents. Many MAC teams’ records are affected by this.
