Biggest Surprise: NC State Advance to the Final Four (0.71%)
NC State's Final Four run was a combination of their own upsets and help from other teams. In the first round, NC State had a 34% chance of winning and pulled off the upset. But, to help, Oakland beat Kentucky (13% chance), giving NC State an easier path forward. The second round went as expected, and NC State kept its roughly 4% chance of advancing. Wolfpack upsets of Marquette and Duke in the next two rounds (28% and 22%, respectively), as well as Duke's upset of Houston (32%) got them into the final four.
Over the tournaments for which I have made predictions, here are the least likely outcomes from each:
Number of Upsets
After a 2019-2020 season where we could only post a tournament what-if scenario, and a 2020-2021 season where limited schedules, game cancelations, and a mix of empty and mostly-empty arenas made accurate predictions nearly impossible, we are back to asking the normal question: Are there more upsets in the NCAA tournament than if these were just regular season games? For this analysis, "upset" is defined by a team with less than a 50% chance (as calculated below) winning its game (generally the same as the betting underdog) rather than based on committee seeding.
For this tournament, the number of upsets was below the expected number of upsets by 0.3, which is well within the bounds of random variability. Across the tournaments since 2015 for which I have made predictions, we have seen 185 upsets in 603 games, vs. a predicted total of 178.1. While higher than predicted, the differential corresponds to 0.5 standard deviations, whcih is not statistically significant.
Below is the combined breakdown of upset statistics, by the likelihood of an upset, over the years tracked.

Selection Notes
As noted in previous seasons, the selections this year largely followed my standard and blended pseudopoll rankings. The pseudopoll correctly predicted 34 of 36 at-large teams, while the standard rankings correctly predicted 33. The one "miss" in both cases was that the computer rankings would have selected Oklahoma and Indiana State over Boise State and Texas A&M. In fact, the NCAA's own NET ranking would have also left Texas A&M out of the tournament, as would have my predictive rankings. It's somewhat unclear what the selection committee saw in Texas A&M. By comparison, my predictive rankings selected 28 of the 36 at-large teams and the NET rankings selected 30.
When it came to seedings, the pseudopoll did the the best overall, with 30 of 68 teams predicted at the correct seed and 53 within one. None of the other rankings predicted more than 26 seeds correctly. A few teams may have some gripes about their seeding: Auburn and Nevada could have easily been seeded two spots (or more) higher based on multiple ranking algorithms.
Prediction Notes
Heading into the tournament, an interesting metric is the relative parity at the top. Top does not mean the #1 seeds, but rather the teams with the best chances of winning. Here is a comparison of the number of teams as a function of likelihood of winning, vs. season.
Season | 5-10% | 10-15% | 15-20% | 20-25% | ≥25% | Winner |
---|---|---|---|---|---|---|
2014-2015 | 2 | 3 | 0 | 0 | 1 | 7.9% |
2015-2016 | 4 | 1 | 1 | 0 | 0 | 5.0% |
2016-2017 | 2 | 2 | 1 | 0 | 0 | 13.2% |
2017-2018 | 4 | 1 | 2 | 0 | 0 | 15.7% |
2018-2019 | 2 | 2 | 2 | 0 | 0 | 19.9% |
2020-2021+ | 3 | 2 | 0 | 1 | 0 | 12.0% |
2021-2022 | 6 | 0 | 0 | 1 | 0 | 16.3% |
2022-2023 | 4 | 1 | 1 | 0 | 0 | 4.2% |
2023-2024 | 3 | 3 | 0 | 1 | 0 | TBD |
In comparison with previous seasons, this season has is tied with the fewest teams with a 15% chance or greater of winning it all. While Houston (22.7%) is the clear favorite relative to any other team, the field has about a nearly 80% chance.
