You’ve probably been there. It’s Saturday afternoon, the wings are cooling on the counter, and you’re staring at a screen where the NFL playoff point spreads look just a little too perfect. Maybe the Seahawks are favored by a touchdown at home, or perhaps the Bills are laying a slim point and a half on the road in the thin air of Denver. It feels like a trap. Honestly, it usually is.
Point spreads in the postseason aren't like the ones you see in Week 4. By January, the "noise" of the regular season—the blowout wins against bottom-feeders and the fluke injuries—has been chewed up by the market. What’s left is a number so sharp it could cut glass.
The Myth of the "Easy" Favorite
Most people think the higher seed is a lock to cover. They see a 14-3 team hosting a wildcard squad and assume a blowout is coming. But look at the 2026 Divisional Round. The top-seeded Denver Broncos just hosted the Buffalo Bills as 1.5-point favorites. The final score? Broncos 33, Bills 30. Denver won, but if you bet on them to cover a spread that moved toward -2.5 at some books, you were sweating bullets until the final whistle.
That’s the thing about the playoffs. The talent gap shrinks. In the regular season, you might have a spread of 14 or 17 points when a juggernaut plays a basement dweller. In the playoffs, finding a spread north of a touchdown is rare. When you do, like the Seattle Seahawks being -7 against the San Francisco 49ers this weekend, it’s usually because of a massive situational advantage, like the "12th Man" noise at Lumen Field.

Why the Number 3 is Your Best Friend (and Worst Enemy)
If you’re looking at NFL playoff point spreads, you’ll notice the number 3 everywhere. It’s the "key number" because so many NFL games are decided by a field goal.
Take the Houston Texans vs. New England Patriots matchup today. The line is sitting right at Patriots -3.
- If New England wins by 4, the "favorite" bettors win.
- If New England wins by 2 or the Texans win outright, the "underdog" bettors win.
- If it’s exactly 3? It’s a push. Everyone gets their money back.
Books hate pushes. They’ll often move the juice (the -110 or -120 you see next to the spread) to entice people to take one side, or they’ll move the line to 3.5. That extra half-point, known as the "hook," is where the real drama happens. A +3.5 underdog is a gold mine in the playoffs because it covers the most common margin of victory in football history.
Historical Shockers That Broke the Books
We can’t talk about spreads without mentioning the times the world went sideways. Everyone remembers the 2002 Super Bowl. The St. Louis Rams, the "Greatest Show on Turf," were 14-point favorites against a young kid named Tom Brady and the Patriots.
Nobody gave New England a chance.
The Patriots didn't just cover the 14 points; they won the game outright. More recently, in the 2012 Divisional Round, the Broncos were 9-point favorites over the Ravens. Joe Flacco threw a miracle "Mile High Salute" touchdown, and the spread became a footnote in history as Baltimore advanced.
The lesson? High spreads in the playoffs are often inflated by "public money." Fans love betting on favorites. It feels safer. Because of that, oddsmakers sometimes nudge a spread from -6 to -7.5 just to balance the books, giving sharp bettors a lot of value on the underdog.

The Home Field Factor in 2026
Home-field advantage used to be an automatic 3 points. Not anymore.
In the 2026 postseason, we’re seeing a shift. The Los Angeles Rams are 3.5-point favorites on the road against the Chicago Bears at Soldier Field. That tells you the oddsmakers think the Rams are roughly a touchdown better than the Bears on a neutral field. It’s a sign of how much respect the market has for Sean McVay’s offense, even in the freezing Chicago wind.
How to Read the "Vig" and Line Movement
You’ve got to watch the "juice." If you see a line like Patriots -3 (-120), it means you have to bet $120 to win $100. The book is telling you they are seeing way too much money on New England and are trying to make it expensive to bet on them without actually moving the line to 3.5.
Wait for the movement.
Sharp bettors (the pros) usually bet early in the week when the lines open. The "public" (regular fans) usually bets on Saturday and Sunday. If a line moves from -3 to -4 on a Sunday morning, it’s often because of a flood of casual bets. That’s usually the best time to "fade the public" and take the points with the underdog.
Weather and Totals
The spread doesn't live in a vacuum. It’s tied to the Over/Under. In the Bills-Broncos game, the total was 45.5. When the total is low, points are harder to come by, which makes every point in the spread more valuable. Being a 3-point underdog in a game with a total of 38 is much better than being a 3-point underdog in a game with a total of 55.
Actionable Strategy for This Weekend
Stop looking for the "winner" and start looking for the "value."

- Hunt for +3.5. If you can find an underdog getting the hook on a key number, take it. This year, the Rams-Bears game at +3.5 for Chicago is a classic "trap" spread that looks tempting for both sides.
- Check the Injury Report Late. In the playoffs, teams hide injuries until the last possible second. A star left tackle being out can swing a point spread by 1.5 points instantly.
- Fade the "Storyline" Team. Is everyone talking about a "team of destiny"? That's usually a sign the spread is inflated. The Texans have a lot of hype right now, which is why they are only +3 against a battle-hardened Patriots team in Foxborough.
- Watch the Wind. Rain is fine. Snow is fun. But wind over 15 mph kills the passing game. If the wind is howling, the underdog is usually the play because the game turns into a low-scoring grind where nobody covers a large spread.
Betting on NFL playoff point spreads isn't about being right about who wins. It’s about being right about how much they win by. Respect the number, watch the juice, and never—ever—bet more than you can afford to lose while watching a kicker miss a 40-yarder in the snow.
Keep an eye on the line movement for the Conference Championships next week. If the Seahawks advance, expect them to be heavy home favorites again, but remember that divisional rivals like the Rams have already proven they can stay within the number even in a loud stadium.
