“No system is perfect,” CIF Southern Section assistant commissioner Jerry De Fabiis said.

That was his response to all the gripes from basketball coaches and administrators this past week as the winter playoffs started. He’s right — and we all know it.

There have been numerous systems in the past to determine playoff divisions and seeding for various sports. In recent memory, the section used school enrollment, geography, and previous-two-years data to create the playoffs.

The last two basketball seasons, the CIF has used ‘competitive equity’ to determine the playoff divisions using computer rankings that rate a team based on data from the current year. The system has been used for football the last handful of years.

Many coaches and administrators have gripes about the computer system, and De Fabiis is actively listening. In fact, on Feb. 7 De Fabiis shared tweaks the CIF Southern Section could make as soon as next season. One being a composite ranking that would combine Massey ratings, High School On SI ratings, and MaxPreps ratings.

“With a composite, you can take care of outliers. That might be the way to go,” De Fabiis said on FATTAL FACTOR. “We always have a debriefing meeting inside the office and with the committees. I know it’s something we’ve kicked around and something we’ll look at.”

With that said, I took the liberty of looking at all three rating systems once the 2025-26 regular season concluded and simply asking ChatGPT to create a composite ranking using all three systems for the Top 100 teams in the CIF Southern Secton.

Here’s what it created …

Here are some bullet points from each system and the composite rankings that are significant when comparing to High School On SI rankings used this postseason.

IMPORTANT: Through SBLive’s access to CIFSShome, accurate Massey ratings with complete data produced the following Top 100. Masseyratings.com external rankings page does NOT have complete data.

Below is a composite ranking that takes the average of Massey, High School On SI and MaxPreps. Further down you’ll see the Top 100 for each rating system.
