Chasing NFL Playoff Perfection (Part 3)

After the all-time (horrific) performance that I had last week, calling this "Chasing Playoff Perfection" is as disingenuous as it gets. Whatever confidence I built during Wild Card Weekend did not just crack in the divisional round. It collapsed. I went 1–3, which somehow feels worse than it sounds, and I am fully aware that this blog series is now being held together by denial and blind optimism.

The only thing that saved me from complete embarrassment was the Rams beating the Bears, and even that came with a full hour of stress as Los Angeles tried its hardest to give the game away. Everything else went off the rails. Josh Allen turned the ball over four times and erased any universe where the Bills were supposed to survive. C.J. Stroud followed with a first-half horror show, four interceptions, and one of the worst single-game passer ratings since 2000, all while Houston’s defense desperately tried to drag him across the finish line. And then there was San Francisco, which was never really a game. Injuries piled up, Christian McCaffrey went down, and Rashid Shaheed returned a punt for a touchdown, scoring as many points in twelve seconds as the 49ers managed all evening.

So here we are. The data failed. The model blinked. The chaos won. But the playoffs do not wait for your ego to recover, and neither does the conference championship round. Perfection is gone. Pride is hanging by a thread. And somehow, against all better judgment, I am back again.

Conference Championships Weekend

Data

The data has not changed. No tweaks, no last-minute overcorrections, no pretending the data was the problem. Changing things now would only muddy the story. If you want a full breakdown of the inputs, sources, and metrics behind these picks, the previous predictions lay it all out. Same data, same rules, same consequences.

Model

The Conference Championship model just got a subtle but powerful upgrade, and it shows in the numbers. It’s still good old logistic regression, but now it uses GroupKFold cross-validation to test on full seasons instead of splitting teams in quirky ways (Leave One Group Out). That means the model’s predictions better reflect real matchups, making the AUC scores more trustworthy. And the feature weights now line up perfectly with what the model is actually using, so every stat in the spreadsheet tells a true story about playoff impact.

The results are eye-popping: Fold 1 through 3 hit a perfect AUC of 1.0, and Fold 4 came in at 0.75. The mean AUC is a stellar 0.9375 with a standard deviation of 0.1083. Cleaner, sharper, and more reliable, the model now not only predicts winners but explains why they have a shot.

Results

Once the conference championship model was locked in, the story snapped into focus. This round does not reward flashy drives or big stats. It rewards discipline. The numbers favor teams that avoid mistakes, capitalize when points are available, and force opponents into situations they are not ready for.

Penalties screamed the loudest at -0.87. One mental error, one sloppy play, and the game swings hard. Efficiency beats volume. Scoring matters, but only when it comes without self-inflicted damage.

Defense quietly carried the rest of the weight. Defensive EPA vs. the run and 3rd Down % allowed both checked in at +0.41, showing that stopping opponents when it counts and making them earn every first down still move the needle. Field-goal % allowed came in at +0.40, another reminder that every drive that does not reach the scoring range is an opportunity to tilt the game in your favor.

The message is clear. Winning here is about staying clean, making the opponent pay for mistakes, and thriving in high-pressure moments. All the flash and hype fade when the field narrows, and every single possession carries weight.

Conference Championship Predictions

Reasons

New England Patriots: Must I give a reason? Against all odds, Drake Maye (a 2nd-year QB) and his Patriots are FAVORED in this game!!! Reminder, this game is occurring in Denver!! Perhaps if it were Bo Nix starting instead of Jarrett "The Javelin" Stidham, Denver would be the dominant force. Stidham hasn't thrown an NFL pass in 2 years. I don't think it's likely that he comes in against a good Patriots secondary and creates some magic. Denver's running game will be the deciding factor, and unfortunately for them, it hasn't been on fire.

Los Angeles Rams: Like many, I believe this is the Super Bowl before the Super Bowl. These have consistently been the 2 best teams in the league this year, but the Rams and Matt Stafford will head on to the Super Bowl on the backs of a great offensive performance. Stafford had 450+ yards the 2nd time these teams played, and that game required a lot of miracles for the Seahawks to pull it out. I simply do not think history repeats itself in that manner.
