Patriots 29, Bills 26: Underdogs Went 8-4-2 in Week 4

New England beat Buffalo 29-26 in Buffalo on Sunday, October 4, 2026, as a 6.5-point underdog. It was the biggest upset of an afternoon in which NFL Week 4 underdogs finished 8-4-2 against the spread and produced five outright winners, including Carolina beating Detroit 32-26 as a three-point dog. Our card returned 35.7 units: $137,588 wagered returned $141,158.45.

The day before this one cost us 102.7 units on a college Saturday. This article is partly about why the two days went in opposite directions.

What Happened

New England 29, Buffalo 26. A 6.5-point road underdog winning outright in Buffalo, against a Bills team that had opened the season looking like one of the better outfits in the conference.

Carolina 32, Detroit 26. A three-point underdog beating a Detroit side most people had rated well above them.

Across the full slate, underdogs went 8-4-2 against the spread with five outright upsets. That is not a day where a couple of results went sideways. That is the entire board leaning one direction.

Why the NFL Pays and College Saturdays Have Not

This is the comparison worth your attention, because the same conditions produced opposite outcomes 24 hours apart.

Both days featured favourites losing. On Saturday that destroyed us. On Sunday it paid.

The difference is what the live model is wrong about.

In the NFL, team ratings are built from years of data on stable rosters against a common opponent pool. Those ratings are largely correct. What moves wrong is the in-game price, because a model that knows Buffalo is better keeps expecting Buffalo to reassert, and prices each possession accordingly. When Buffalo does not reassert, there is a real and repeated gap between the price and the game. We bet that gap and it pays.

In college football this season, the ratings themselves have been wrong. A No. 8 losing by 28 to a No. 25 is not a live-pricing lag, it is a pregame rating that was never right. When the underlying rating is the error, there is no gap between the model and reality to exploit, because the model and the bettor are making the same mistake at the same time.

Short version: we make money when the market is right about talent and slow about the moment. We lose money when the market is wrong about talent, because the live number inherits that and so do we.

That distinction is the single most useful thing on this page, and it is why the NFL picks card has been consistently positive while college Saturdays have not.

The Documented Day

Worth noting that this was a good day, not a spectacular one, on a very large card. A 35.7 unit return on $137,588 is a thin margin. That is what a normal profitable Sunday actually looks like, and it is a long way from the 110.6 unit Sunday three weeks earlier. Both are on the results page.

What This Game Teaches About Football Handicapping

8-4-2 is a market-wide signal, not twelve separate reads. When underdogs cover two-thirds of a slate, something systematic is happening to the week's numbers rather than to individual games. Usually it means the previous week's results have been over-weighted, pushing favourites a point or two further than they deserve across the board. That is a condition you can act on before kickoff, not a pattern to notice afterwards.

Road underdogs in hostile buildings are the most over-corrected number in football. Buffalo at home against New England is exactly the kind of matchup where the crowd, the travel and the recent form all push the number in the same direction. Three factors pointing one way is how a line gets a point too long. Anyone selling football betting picks should be hunting those stacked-narrative spots rather than avoiding them.

Know which sport your edge actually lives in. This is the lesson from the weekend as a whole. Our NFL card has been reliably positive and our college Saturdays have lost three in a row at increasing size. A serious approach to football handicapping means letting the ledger tell you where the edge is rather than betting every sport because every sport is on.

That last point is also the honest filter for judging sports handicappers: does their card concentrate where their results are, or does it spread across everything on television? Breadth usually signals a service selling volume rather than edge.

Why Week 4 Specifically Produces Underdog Days

There is a seasonal reason an 8-4-2 underdog slate shows up at this point in the calendar rather than in November.

By Week 4 the market has three games of current data on every team, which feels like enough and is not. Three games is a small sample against three opponents whose own quality is still unknown. A team that has started 3-0 against soft opposition gets rated as a 3-0 team. A team that has lost close games to good opponents gets rated as a 1-2 team.

The market knows this in principle and still over-weights it, because three games of real evidence is psychologically far more compelling than zero. Week 1 numbers carry obvious uncertainty and get priced cautiously. Week 4 numbers carry hidden uncertainty and get priced confidently.

Confident and wrong is the most profitable combination a bettor can find, and early October is where it concentrates.

The practical version. Through roughly Week 6, look hardest at favourites whose rating is built on a soft opening schedule, and at underdogs who have lost narrowly to good teams. By midseason the schedule has evened out and this edge closes. It is one of the few genuinely seasonal patterns in daily sports betting picks, and it is available for about six weeks a year.

What This Doesn't Prove

A 35.7 unit Sunday is a good day and nothing more.

It does not undo the Saturday before it, which lost 102.7 units on a larger card. The weekend as a whole was deeply negative, and presenting this article without that context would be exactly the kind of selective reporting this site exists to argue against.

October currently stands at −45.1 units. September finished at +205.7. Both numbers are published, and the losing days inside them are published at full size.

We are not claiming a win rate. Past results do not guarantee future performance.

Frequently Asked Questions

What was the biggest NFL upset on October 4, 2026?

New England beating Buffalo 29-26 in Buffalo as a 6.5-point underdog. Carolina beating Detroit 32-26 as a three-point underdog was the other notable outright upset.

How much did The Best Bet on Sports make on October 4?

$3,570.45 on $137,588 wagered, which is 35.7 units at $100 a unit. The FanDuel statement is published with it.

Why does the NFL card perform better than college Saturdays?

Because the errors are different. NFL team ratings are largely accurate and the in-game price is slow, which creates a gap worth betting. In college football this season the pregame ratings themselves have been wrong, so the live price inherits the error and there is no gap to exploit.

What does an 8-4-2 underdog day signal?

Usually that the week's numbers over-weighted recent results, pushing favourites a point or two too far across the whole board. It is a market-wide condition rather than twelve independent outcomes.

Are road underdogs in loud stadiums good value?

Often, because crowd, travel and recent form all push a number the same direction at once. When several narratives stack, lines tend to move further than the underlying probability justifies.
