Buh bye, RPI: The NCAA created its own metric

The NCAA is ditching the RPI for its own metric system.

The new NCAA Evaluation Tool, which will be called the “NET,” will be the primary tool for sorting, evaluating and ranking teams, beginning this upcoming season. The NET will rely on game results, strength of schedule, game location, scoring margin, net offensive and defensive efficiency, and the quality of wins and losses, according to its explanation on the NCAA’s website here.

Dan Gavitt, senior vice president of basketball for the NCAA, said, “What has been developed is a contemporary method of looking at teams analytically, using results-based and predictive metrics that will assist the Men’s Basketball Committee as it reviews games throughout the season. While no perfect rankings exist, using the results of past tournaments will help ensure that the rankings are built on an objective source of truth.”

There is a lot to digest in the analytics behind the NET and I’m not the guy to do it, but it’s worth noting that margin of victory will matter. In years past, it hasn’t really mattered if a team lost by 1 or 21, but now scoring margin is factored in. The margin will be capped at 10 points, though, to not reward running up the score when a game is out of reach.

The NET will be updated on a weekly basis throughout the season.

It was nice knowing you, RPI.

    How will this affect DJ Jeffries and his father?

    Hmmm… how will this affect the “darlings” of the NCAA such as UNC and other schools? That is the question!

    10 seems like a low cap. A close game can easily be pushed to 10 with free throws and the millions of timeouts that will be called.

      Agree. I was thinking 15.

    It is an improvement from the RPI format but not much of one. There a a few flaws in the NET system the cap of 10 is going to be really hard to manage even for the computers. It also allows the NCAA the power to be bias towards specific teams like Duke or NC for example. However it will make it easier for the Selection committee when it comes to comparing bubble teams for the NCAA Tournament. UK however will better benefit from the NET system this upcoming season because of thier tough Non-Confrence schedule, and a much stronger SEC conference as long as the cats take care of business.

    This could make these early season tough games much more important for our seeding in March. I wonder if this will deter teams from scheduling these type of games in November.

    One of the hardest undertakings in statistics is basing predictive algorithms on subjective data and getting reliable results. Compound that with a relatively limited data set, like 347 teams who play less than 10% of the other teams in a given season, and you’re going to have glaring flaws by the end.

    Even Ken Pomeroy, who is basically a wizard, struggles with developing a good predictive algorithm. I used his matchup predictor system to fill out a bracket for last year’s tournament just for fun… according to his predictions UVA was supposed to win it all, not hold the most infamous L in tournament history.

    The metric also favors coaches who have a higher concentration of consonants packed into their last names. #krzyzewski

    If the point margin is so important, will our bench guys ever get in?

      +30 with a minute to go, yep

    NCAA created? Does this mean UNC will have a different algorithm?
