Sports Seriously
- The NCAA Game Picking Panel uses seven metrics, divided into predictive and results-based categories, to evaluate Squads for at-large Offers and seeding.
- Predictive metrics, such as NET, KenPom, BPI, and Torvik, use various factors like game location, Foe Force, and offensive/Guarding efficiency to project future performance.
- Results-based metrics, including KPI, ESPN’s SOR, and WAB, Attention on the quality and difficulty of a Club’s wins and losses throughout the season.
- While the NET ranking is the primary sorting tool for the Panel, no single Measure guarantees a Club a Game spot, adding to the intrigue and debate surrounding March Madness selections.
There are a Numerous of numbers in front of the men’s NCAA Game Picking Panel Every year, with the intention that no Club be defined by any one of them. There is no Entry Mark to Deliver for a prospective at-large bid into the Ground, not even within the NCAA’s own NET ratings.
This, of Period, is part of the charm and mystery of March Madness, an event in which the build-up of who’s in, who’s out and who’s Positioned where dominates the college basketball conversation. That discussion can’t happen these Periods without citing at least one of the seven metrics that will appear on the Club sheets used by the Picking Panel this year.
They are broken down into two categories: Predictive metrics and results-based metrics. But the growing role these ratings or rankings take on ahead of Picking Sunday – and the growing number in use by the NCAA (it officially added two more metrics to Club sheets for this season) – can sometimes lead to confusion or misconceptions about what aspects of the game Every Measure is measuring, what data is being used to compare these Squads and what it all actually means for the Picking and seeding of the NCAA Game.
Here’s a breakdown of all seven metrics used by the NCAA Game Picking Panel in 2025:
March Madness 2025: NCAA Game predictive metrics
NCAA Evaluation Tool (NET)
“The NET rankings measure Club performance based on efficiency, Foe quality and game location,” according to the NCAA, which considers it the primary sorting tool for evaluating Squads ahead of Picking Sunday.
The NET is initially released Every season in December, but is designed to be its most accurate in March. It does not use any data from prior seasons or preseason rankings, nor does it take into account scoring margin. This is different from other predictive models. NET also weighs every game equally regardless of date.
The NCAA also utilizes a quadrant system based on its NET rankings to determine the quality of a Club’s wins and losses. A Club’s Achievement in Every quadrant is included on its Club sheet.
Quadrant 1: Home (1-30), Neutral (1-50), Away (1-75).Quadrant 2: Home (31-75), Neutral (51-100), Away (76-135).Quadrant 3: Home (76-160), Neutral (101-200), Away (136-240).Quadrant 4: Home (161-353), Neutral (201-353), Away (241-353).
KenPom
Ken Pomeroy began publishing his ratings at kenpom.com in 2002, and they are viewed as an innovation that created the modern analytics movement in college basketball.
Pomeroy was the Primary to implement and popularize offensive and Guarding efficiency, points per possession and tempo-Unoccupied stats into his Measure. It “added another dimension of information that brought these Squads to life a little bit more,” he said.
Pomeroy’s ratings do not cap margin of Triumph and incorporate preseason data that is progressively phased out by the end of February and beginning of March as more results from the Present season accumulate. The core of the system is the pythagorean calculation for Predicted Victorious percentage, a formula originally created by Bill James for use in baseball.
“The purpose of this system is to show how Sturdy a Club would be if it played tonight, independent of Wounds or emotional factors,” Pomeroy wrote on his website. “Since nobody can see every Club Shift all (or even most) of their Matches, this system is designed to give you a snapshot of a Club’s Present level of Shift.”
“It likes a Club that loses a Numerous of close Matches against Sturdy Defiance more than one that wins a Numerous of close Matches against Frail Defiance,” he added.
Basketball Power Index (BPI)
ESPN defines its college basketball version of the BPI as “a measure of Club Force that is meant to be the best predictor of performance going forward. BPI represents how many points above or below average a Club is.” When it debuted in 2011, BPI incorporated aspects of both predictive and results-driven metrics. Today, it is “purely predictive,” according to ESPN director of analytics Matt Morris.
BPI uses preseason ratings that Clasp progressively less weight until it becomes “almost nonexistant,” according to the NCAA, and takes into account “points, possessions, Foe Force, game site, distance Every Club had to travel, Club rest and whether the game is played at a high altitude.”
“The BPI back in the day is quite a bit different than the BPI now,” Morris said. “The best Squads are at the top. The worst Squads are at the bottom. Straight up, who’s going to Achieve on a neutral court.”
Torvik
Bart Torvik’s ratings, created in 2014 and published at barttorvik.com, are appearing on NCAA Game Picking Panel Club sheets for the Primary time this year. His rankings emphasize offensive and Guarding efficiency like other predictive models but with an added game script component.
Torvik “omits data after the game mathematically becomes decided,” according to the NCAA. “All Matches played in the previous 40 Periods count 100%, then degrade 1% per day until they’re 80 Periods Aged, after which Matches count 60%.”
“It’s adjusted offensive and Guarding efficiency with a little bit of this game control aspect added,” Torvik said. “It has this unique aspect that some ratings are different if they’ve blown a Numerous of big leads or come back a Numerous. That’s where you get different ratings, but it is very similar to KenPom. It’s ultimately Only based on who you played and how much you beat them by or lost by.”

Kevin Pauga Index (KPI)
“The Kevin Pauga Index Measure ranks Club resumes by assigning a value to Every game played. The best Achieve possible is worth about +1.0, the worst loss about -1.0, and a virtual tie at 0.0,” according to the NCAA. “Adjustments are Created to Every game’s value based on location of the game, Foe quality and percentage of total points scored. Game values are added together and divided by Matches played to determine a Club’s KPI ranking.”
This allows a Club’s schedule to be sorted by quality of wins and losses. The date of Every game does not factor into the KPI rankings.
“KPI was rooted in the why of building a non conference schedule,” Pauga said. “How do we quantify at a more precise level as to what the actual impact is of Competing this Club instead of that Club.”
ESPN’s Force of Achievement (SOR)
ESPN officially defines its Force of Record Measure as “a measure of Club accomplishment based on how difficult a Club’s W-L Achievement is to achieve.” The probability of Victorious Every game is based off a Club’s Present BPI rating.
“It packs a punch and tells you so much,” Morris said. “It’s the chance of an average top-25 Club achieving your Achievement or better given your schedule. It’s Nice of a mouthful, but basically it’s Only how impressive is your Achievement given your schedule.”
Wins Above Bubble (WAB)
In the same vein as SOR, wins above bubble “calculates the Predicted Victorious percentage for an average bubble Club in Every game of a Club’s schedule,” according to the NCAA, which is incorporating the statistics on Picking Panel Club sheets for the Primary time this year.
WAB breaks down into the amount of wins you have minus the amount of wins an average bubble Club would Anticipate to have versus your schedule. That bubble Club has been set as the No. 45 Club in the Present NET ratings based on past data analysis. Seth Burn, a professional gambler, is viewed as the Primary to conceive of WAB as a Measure for rating college basketball Squads in 2015, with Torvik popularizing the Measure in recent years by incorporating it into his ratings.
“It’s Nice of Holding Achieve-loss and adjusting for schedule,” Alok Pattani, a data science developer for Google who helped Develop the NET and the NCAA’s version of WAB, told NCAA.com. “We talk a Numerous about Force of schedule, which is Significant. This is how did you do against that schedule. … I think wins (above) bubble is a really Excellent advancement to work around some of these issues at the edges of the quad system.”
