Week 3 NFL betting is a lot like Week 2: Overreactions run rampant, and underdogs reign supreme.
According to our Action Labs data, underdogs are 145-117-6 (55.3%) in Week 3 since 2005, beating the spread by an average of 1.68 points per game. Blindly betting every Week 3 dog over that span would have netted you an 8.4% ROI, which is pretty impressive for such a broad trend over such a long period of time. Of course, there will always be spots we can target to get that win rate even higher.
Below are five A-graded Week 3 trends that have cashed at least 60% of the time for the last decade-plus.
NFL Week 3 Betting Trends
Week 3 Dogs +7 or Less vs. Favorite with Negative ATS Margin
Just like point differential is more predictive than winning percentage, ATS differential can be more predictive than ATS record.
Week 3 Dogs that are already expected to lose by no more than a touchdown tend to be undervalued against favorites with a negative ATS margin. There's a lot of luck involved in football, and early in the season, it's easy to mistake some of that luck for skill.
Since 2006, dogs in this spot have gone 57-29-2 (66%), beating the closing line by an average of 3.84 points per game.
These dogs have been profitable at home (16-10; 62%), but even more so on the road (41-19-2; 68%).
Six teams fit this trend in 2022:
- Panthers +2.5 vs. Saints
- Falcons +1 at Seahawks
- Jets +6 vs. Bengals
- Titans +2 vs. Raiders
- Cardinals +3.5 vs. Rams
- Broncos +1.5 vs. 49ers
Week 3 Dogs With At Least One ATS Loss That Opened Under a TD
Though ATS differential gives us the strongest trend, the market can be overly pessimistic on Week 3 dogs that have failed to cover at least once in the young season.
Since 2005, Week 3 dogs with at least one ATS loss that opened under a touchdown are 89-54-2 (62%) ATS, beating the closing number by an average of 2.61 points per game.
Dogs that fit this trend are 26-17-1 (60%) at home, 56-33-1 (63%) on the road, and 1-0 at neutral sites.
The last time this trend failed to have a profitable year was 2015. Since 2016, it has gone 33-17 (66%).
Five teams fit this trend in 2022:
- Colts +5.5 vs. Chiefs
- Panthers +2.5 vs. Saints
- Jets +6 vs. Bengals
- Cardinals +3.5 vs. Rams
- Packers +1 at Buccaneers
Winless Week 3 Dogs +1.5 to +7
Being a winless team heading into Week 3 is the worst. The entire fanbase is sentenced to death by 1,000 "teams that start 0-2 only make the playoffs 2-point-never percent of the time" cuts.
If the team is a dog in Week 3, forget about it, the sky is falling. Except it is't — at least when it comes to covering the spread, that is.
Since 2005, dogs +1.5 to +7 that are winless entering Week 3 have gone 40-26-2 (62%).
This trend has been profitable in each of the past six years, registering a record of 23-8 (74%) over that span.
Four teams fit this trend in 2022:
- Colts +5.5 vs. Chiefs
- Texans +3 at Bears
- Panthers +2.5 vs. Saints
- Titans +2 vs. Raiders
Week 3 Dogs vs. Favorites That Covered for the First Time in Week 2
This is a classic recency bias trend. A favorite that covered in Week 2 after not covering in Week 1 is often viewed to be improving or getting on the right track after a rough start despite a sample size of only two.
Dogs in this spot have gone 62-39-4 (61%) ATS since 2005, beating the spread by an average of 2.61 points per game.
This trend holds as long as the line has moved more than 3 points in either direction from open, which would suggest something beyond typical market factors is influencing the line, such as a quarterback injury.
No teams fit this trend this season, but it went 5-2 in 2021 and is worth filing away for the future.
Week 3 Home Teams vs. Visitors With At Least One Win
This trend doesn't apply to just dogs. All winless home teams hosting a visitor with at least one win on the season have gone 31-19-2 (62%) ATS since 2005, beating the spread by an average of 1.77 points per game.
This trend doesn't come up often, but it's 11-5 (69%) over the past five seasons.
Two teams fit this trend in 2022:
- Colts +5.5 vs. Chiefs
- Panthers +2.5 vs. Saints
