NCAA removing winning %, scoring margin from NET formula; new formula all efficiency based

NET will likely now be close to a carbon copy of KenPom with the only difference being teams who perform better on the road being higher in NET than on KP.

quote:

The adjusted efficiency is a team’s net efficiency, adjusted for strength of opponent and location (home/away/neutral) across all games played. 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.

No longer will the NET use winning percentage, adjusted winning percentage and scoring margin. The change was made after the committee consulted with Google Cloud Professional Services, which worked with the NCAA to develop the original NET.

Not a huge fan of this as KP is supposed to be predictive. And while KenPom is the best way to gauge a team's strength I think NET should be heavily W/L results based. Really will negatively impact the teams that win tons of close games like AU last year and LSU the year before.

Will be interesting to see how the committee deals with teams that "over-perform" and if they are actually punished.

The scoring margin was stupid to begin with
Winning by 10 was worth more
It still rewards you for your schedule which is what it should do

Yea, don't like this at all. It's good to have some efficiency stuff in there, but it should not be entirely efficiency-based.

On the flip side, Alabama loses every close game we play so this is a big plus for us!

I don’t like this for much of the same reasons you don’t like it. KenPom doesn’t rate resumes, it predicts the quality of the team.

Give me results stemming from W/L over how good a team is on paper.

Agree - I like the efficiencies as a way to compare teams with similar win/losses or as a piece of the puzzle, but you can't just take KenPom and use it to pick a field. I don't even think Pomeroy would say that is the point of his system. It's not a rating of resumes, it's a tool to judge how "good" a team is.

If we'd done it last year all the Top 8 seeds would be teams from the B1G. Pretty sure Minnesota would be a 5 seed with a .500 record.

Didn't we move away from the RPI in large part because it incentivized losing to good teams too much instead of rewarding winning?

I look forward to the B1G getting 80% of their league into the tournament the next five years. Yay parity!

How does it impact the teams they beat? Like Tennessee. What does this do to Tennessee?

Tennessee has finished higher in the NET than KP both years as well. In 2019 Tennessee finished 5th in NET and 7th in KenPom and got a 2 seed so not much of an impact.

There will be 21 teams from the B1G/B12

It's crazy that people hated the RPI and then the NCAA went and replaced it with something worse

The formulas are exhausting. They've become too finite and statistically dependent to be objective. Every time a model or formula is changed, the approach to use them seems less relevant.
