The 2025 NCAA Division I men's basketball tournament is here. The 68-team bracket was officially released on Sunday evening, and over the next 72+ hours, anywhere from 60–100 million brackets will be filled out ahead of the First Round tipping off on Thursday afternoon.
But who should you pick to win it all? Well, it's complicated. While March Madness is known for its last-second buzzer-beaters, upsets, and unlikely Cinderella runs, more often than not the tournament champion still ends up being a powerhouse.
In fact, since 1999, 18 of the tournament's 25 champions have been a No. 1 seed—one of the top-four teams in the country. On top of this, since 2002, all but two Madness champs have been a top 20 team in both adjusted offensive rating and adjusted defensive rating according to KenPom.
What's KenPom? I'm glad you asked. Let's dive in.
What is KenPom?
College basketball's KenPom rankings were created in 2002 by Ken Pomeroy, a former meteorologist turned instructor of atmospheric sciences at the University of Utah.
Pomeroy uses his own website (KenPom.com) to publish statistics that measure adjusted offensive and defensive efficiency, tempo, luck and strength of schedule—which are ultimately calculated into KenPom ratings.
Originally created as a personal venture, Pomeroy's stats have turned into a college hoops phenomenon. The rankings and numbers are not only widely recognized by sports media and news outlets, but are also used by teams across the country who hope to gain a competitive advantage.
Below is a look at the nation's top 20 according to KenPom, as well as the top 20 in both adjusted offensive and defensive rating—which can generally be used to help narrow down a champion.
2025 KenPom Rankings: Top 20
KenPom's rankings are based on net rating, or "adjusted efficiency margin," which measures how many points a team would outscore an average opponent.

Florida Gators (No. 1, West Region)Auburn Tigers (No. 1, South Region)Duke Blue Devils (No. 1, East Region)Houston Cougars (No. 1, Midwest Region)Tennessee Volunteers (No. 2, Midwest Region)Iowa State Cyclones (No. 3, South Region)
