I'll highly contest that any strategy like this could be profitable after the vig. You're not just saying that KenPom is bad, but that the betting line is systematically incorrectly swayed by KenPom/metrics across enough games that betting the other way is correct >52% of the time. See
https://www.thepredictiontracker.com/bbresults.php (and
2025, don't have a link to 2024,
2023, 2022, and
2021). All the computer rankings in that comparison over several years are within 48-52% (except Torvik at 52.8% one year) against the spread, so no strategy of betting with/against any of these models would be profitable after a 5% vig. KenPom isn't included, but I'm not willing to accept that they're significantly worse than every single other model without proof, so share your source/data, or we'll have to agree to disagree.
If you're just trying to argue that KenPom is less accurate than the spread, then of course it is (especially early in the season and games affected by injuries). But it isn't helpful at predicting anything against the spread.
You appear to be wrong and right at the same time...
You're wrong in that they did not go 17-1 in 18 coin flips. They were given a 6-7% chance to win it all in 2023 and 20-22% in 2024 (elevated above Torvik's odds of 15%, so betting markets started accounting for something extra). Combined, that's 1.2-1.5%. But in 2023, the best teams they faced were #9, #10, and #11 in Torvik (3 and 5-seeds; while seeding is pretty inaccurate, it gives a perspective on their actual vs likely path). In 2024, other than Purdue (#3, 1-seed), the best they faced were #13 & #14 (3 and 4-seeds). So with those paths their odds would have been much higher, though I don't have time to figure out what. It's still very impressive, but probably more like 20 to 1 than 13,797 to 1. In 2025, they beat Oklahoma as a ~70% favorite and lost to Florida with a ~20% chance to win. So he didn't work any magic there.
But I've also read that they went 17-1 against the spread in those games, so in that regard your calculations are right. Yet what matters isn't how Hurley did vs betting markets in 2023 or 2024, but whether this year's betting markets are meaningful. FWIW, that one loss against the spread was Furman this year, and altogether this year, they're averaging 1.75 points better than the spread, which I'm willing to guess is
much less than in 2023 or 2024, so either betting markets have adjusted, or UConn's NCAAT magic has regressed compared to 2023/24.
Well now we agree
