While a team’s strength of schedule can give you an idea about how they stack up to competition, how do you know if a team has quality wins or losses?
Tiers can help answer this question.
KenPom defines 2 tiers:
Home court advantage exists in college basketball. KenPom gives a flat 3.75 points for the home team.
For example, in the 2018-2019 season, Virginia would be expected to defeat the average Division-I team by about 34 points on a neutral court.
If Virginia is playing host to the average Division-I team, its AdjEM jumps to about +37. This means at home, Virginia would be expected to defeat the average Division-I team by about 37 points.
This is why adjusting for location is important.
Beating the 90th-ranked team on the road is about as difficult as beating the 50th-best team on a neutral floor, which is roughly as difficult as beating the 20th-best team on one’s home floor.
KenPom does hint towards sharing site-specific home-court advantage values in the future too.
Since 1981, the RPI (Rating Percentage Index) was used by the NCAA Selection Committee as one of the main factors in determining at-large selections for the NCAA Tournament.
The NCAA replaced the RPI with the NET (NCAA Evaluation Tool) entering the 2018-19 season. Jordan Sperber does a great job breaking down improvements in this video.
