Power-rating comparison
NFC South math: Saints at Buccaneers
New Orleans Saints at Tampa Bay Buccaneers is a NFC South game, the first of two meetings, with the rematch in Week 18. The model has the Buccaneers by 4.5 (63%) off a -0.5 to -2.4 rating gap. Division games carry weight the model does not price: head-to-head is the first tiebreaker in the NFC South, so a win here is worth more in January than the standings column shows.
No unit matchup in this game separates by even a point on our scale. The Buccaneers grade +0.5 on offense (18th of 32) and -1.1 on defense (20th); the Saints -1.6 (27th) and -0.5 (14th). Evenly-graded units on both sides of the ball is exactly the profile that produces a model line built from nothing but home field, though special teams does tilt to the Buccaneers (+0.2, 26th).
On the standings side, NFC South games are the ones that decide the tiebreakers. Head-to-head record is the first tiebreaker between two teams in the same division, and division record is the next — so the value of this result is not just the win column. They meet again in Week 18, which makes a sweep the outcome with real leverage on the NFC South race.
Season-long, the model can barely split them: 8.3 projected wins for the Buccaneers against 7.7 for the Saints, favored in 7 and 7 of their 17 respectively. Two teams heading for the same neighborhood in the standings tend to produce exactly this kind of line. This game sits 16th-hardest on the Buccaneers' schedule and 5th-hardest on the Saints'.
Recent history, for context only: 48 regular-season meetings since 2002, 28-20 in the Saints' favour, plus 1 playoff game. They last met in 2025: Saints won 24-20 in December. Over their last 4 meetings the Buccaneers are 3-1. It is not an input to the line — rosters turn over faster than series records do.
Does the model earn this number? In 666 of the 3266 walk-forward games it has been graded on (2013-2024, no market line used), it landed in the 60-65% range. Those favourites went 59%. The 63% on the Buccaneers here sits in that same band, and the history runs slightly behind the claim.
Kalshi has not listed KXNFLGAME-26DEC20NOTB, so there is no price on the board and no edge to quote. The model's number to hold it to: Buccaneers 63%, Saints 37%. Applying our five-point threshold, that makes Buccaneers contracts a buy at 58c or below and Saints contracts a buy at 32c or below — anything between is inside the noise, and we pass. Week 1's KXNFLGAME contracts opened in May 2026 and the rest of the slate lists as the season gets closer; this page picks up the price automatically when it does.
