Men’s Basketball NET Changes Follow Women’s Announcement


Last week, the NCAA announced that its women’s basketball committee would move to the NCAA Evaluation Tool (NET) as a primary metric in assisting the selection and seeding process for teams in the women’s basketball tournament.

The announcement did have one slightly puzzling aspect, as the women’s version of the NET was billed as using only two of the factors that the men’s version had employed for the past two seasons.

However, late on Monday, the NCAA pulled the two sides of the hoop house back in line with the announcement that the men’s version to be employed in the upcoming season will only use the same two factors.

Gone are the winning percentage, adjusted winning percentage and capped scoring margin factors. Remaining in the NET are the Team Value Index (TVI) and the adjusted net efficiency rating.

According to the NCAA, the TVI is “a result-based feature that rewards teams for beating quality opponents, particularly away from home. The adjusted efficiency is a team’s net efficiency, adjusted for strength of opponent and location (home/away/neutral) across all games played.”

Without question, the location of games played, and winning on the road and on neutral courts, will become even more important in this version of the net, as location is part of both of the remaining metrics.

In last year’s version of the NET, home wins were valued as 0.6 of a win in strength of schedule calculations, while neutral site wins were at 1.0 and road wins at 1.4. While that adjusted winning percentage is no longer included, this year’s version of the NET, employs the same sort of logic. The NCAA expounds:

“For example, a given efficiency value (net points per 100 possessions) against stronger opposition rates higher than the same efficiency against lesser opponents and having a certain efficiency on the road rates higher than the same efficiency at home.

Strength of schedule is also getting a makeover, making it more difficult to pile up strength of schedule points by defeating weak teams on the road. The NET will now rate every game on a team’s schedule for how hard it would be for an NCAA tournament-caliber team to win. It considers opponent strength and site of each game, assigning each game a difficulty score. Aggregating these across all games results in an overall expected win percentage versus a team’s schedule, which can be ranked to get a better measure of the strength of schedule.

The NCAA continues to guard the details of the its TVI and adjusted efficiency metrics, making it impossible to reproduce them or study the effects of different scores or results.
