College basketball has evolved far beyond box scores and win–loss records. In today’s data-driven sports world, advanced analytics play a critical role in evaluating teams, predicting outcomes, and understanding the game at a deeper level. One name dominates this space more than any other: KenPom.
If you’ve ever followed NCAA basketball closely—especially during March Madness—you’ve likely heard analysts, coaches, bettors, and fans reference KenPom rankings. But what exactly is KenPom? How does it work? And why is it considered one of the most accurate tools in college basketball analytics?
This in-depth guide will walk you through everything you need to know about KenPom, from its origins and metrics to how it influences modern basketball analysis.
What Is KenPom?
KenPom is shorthand for Ken Pomeroy’s college basketball analytics system, a data-driven ranking model that evaluates NCAA Division I men’s basketball teams. Created by statistician Ken Pomeroy, the system is hosted on the website KenPom.com and has become one of the most trusted resources in the sport.
Unlike traditional rankings that rely on polls or basic stats, KenPom uses advanced efficiency metrics to measure how well teams perform on a per-possession basis. This approach removes pace bias and provides a more accurate comparison between teams.
In short, KenPom focuses on how good a team actually is, not just how many games it wins.
The History Behind KenPom
Ken Pomeroy launched his analytics website in the early 2000s, initially as a passion project. At the time, advanced basketball analytics were still niche, especially at the college level.
Over time, his predictive accuracy gained attention. Media outlets, coaching staffs, and even the NCAA tournament selection committee began referencing KenPom metrics. Major sports networks like ESPN and CBS frequently cite KenPom rankings during broadcasts.
Today, KenPom is widely regarded as the gold standard for college basketball efficiency analysis.
Why KenPom Is So Popular
KenPom’s popularity stems from three main factors:
- Predictive Accuracy
KenPom consistently performs well at predicting game outcomes, especially when compared to polls and traditional rankings. - Efficiency-Based Analysis
By focusing on possessions rather than raw totals, KenPom eliminates misleading stats caused by fast or slow pace. - Transparency and Depth
The system provides dozens of metrics that allow fans to dig as deep as they want into team performance.
Core KenPom Metrics Explained
To truly understand KenPom, you need to understand its key statistics. Below are the most important metrics and what they mean.
Adjusted Offensive Efficiency (AdjO)
This metric measures how many points a team scores per 100 possessions, adjusted for opponent quality.
- Higher AdjO = more efficient offense
- Accounts for strength of schedule
- One of the strongest indicators of elite teams
Teams with a top-tier AdjO are usually strong contenders in the NCAA Tournament.
Adjusted Defensive Efficiency (AdjD)
Adjusted Defensive Efficiency shows how many points a team allows per 100 possessions, again adjusted for opponent strength.
- Lower AdjD = better defense
- Highlights teams that limit scoring efficiently
- Crucial for tournament success
Historically, teams with elite defenses perform better under pressure.
Adjusted Efficiency Margin (AdjEM)
This is the difference between AdjO and AdjD.
AdjEM = AdjO – AdjD
- The most important KenPom ranking metric
- Used to rank teams overall
- Higher margin = stronger team
When people refer to “KenPom rankings,” they are usually referencing AdjEM.
Tempo
Tempo measures the number of possessions a team uses per 40 minutes.
- High tempo = fast-paced teams
- Low tempo = slower, more deliberate teams
Tempo is essential context. A team scoring fewer points may still be highly efficient if it plays slowly.
Strength of Schedule (SOS)
KenPom evaluates how difficult a team’s schedule is, including both conference and non-conference games.
- Prevents inflated stats from weak schedules
- Helps compare teams across conferences
This is especially useful when evaluating mid-major teams.
How KenPom Adjusts for Opponents
One of KenPom’s greatest strengths is adjustment. Every metric is adjusted based on:
- Opponent quality
- Game location (home, away, neutral)
- Tempo
This means a close loss to a top-ranked team can still improve a team’s KenPom rating, while a narrow win over a weak opponent may hurt it.
This approach explains why KenPom rankings often differ significantly from the AP Top 25.
KenPom vs Traditional Rankings
Many fans wonder why KenPom rankings don’t always match the AP Poll or Coaches Poll. The difference lies in methodology.
| Feature | KenPom | Traditional Polls |
|---|---|---|
| Based on efficiency | Yes | No |
| Adjusts for pace | Yes | No |
| Accounts for opponent quality | Yes | Limited |
| Human bias | None | High |
| Predictive accuracy | Very high | Moderate |
KenPom is designed to predict future performance, not reward past results.
How Coaches and Teams Use KenPom
KenPom isn’t just for fans. Many college basketball coaches use these metrics internally to:
- Prepare scouting reports
- Identify strengths and weaknesses
- Adjust game strategy
- Evaluate recruiting needs
Some programs even employ full analytics departments inspired by KenPom principles.
KenPom and March Madness
No discussion of KenPom is complete without mentioning March Madness.
KenPom rankings are famously effective at identifying:
- Potential Final Four teams
- Dangerous lower seeds
- Upset alerts
Historically, most national champions rank top 20 in KenPom entering the tournament. Many are top 10.
While KenPom can’t predict every upset, it significantly improves bracket accuracy.
KenPom and Sports Betting
KenPom has also become a major tool in college basketball betting.
Bettors use KenPom to:
- Compare projected efficiency margins
- Identify line value
- Analyze matchup mismatches
- Predict totals and spreads
While KenPom alone doesn’t guarantee wins, it provides a powerful data-driven edge when combined with situational analysis.
