NFL Passing Touchdown Props: The Variance Math Behind The Juice
A passing touchdown prop looks like a question about a quarterback. It isn't. Over the last two NFL regular seasons, the average starting quarterback threw exactly 1.50 touchdown passes per game: 1.49 in 2024, 1.51 in 2025, across 1,021 starts. That number barely moves. What moves is which side of it you land on, and that gets decided almost entirely by a handful of snaps inside the 20-yard line.
That stability is the whole story of this market, and it cuts both ways. It is why a sportsbook can post the same line on nearly every quarterback in the league, why the only lever the book has left is the price, and why the juice on passing touchdowns runs worse than what you pay on passing yards. It is also why one signal in pro football actually moves your number, and it isn't the name on the jersey. There's a quarterback in our data who proves that point better than anyone. I'll get to him.
In Summary: The Ten-Second Read
- Starting quarterbacks averaged 1.50 passing touchdowns per game across 1,021 starts in 2024–25. The distribution is almost perfectly Poisson.
- Over 1.5 Passing Touchdowns Hit 45.9% of the time at baseline. That makes the fair price roughly +118, not even money.
- The market is juiced because the line can't move. Passing yards can go from 246.5 to 248.5. Passing touchdowns only has 1.5 and 2.5, and the fair price between them jumps from +118 to about +464. The book adjusts the price instead, so the juice is the adjustment.
- 71.1% Of 2025 Passing Touchdowns Were Thrown From Inside The 20, and 47.7% from inside the 10. This bet is decided in the red zone.
- The real signal is red-zone pass rate, which ranged from 69.2% (Arizona) to 40.1% (Baltimore, Washington) in 2025. That 29-point spread dwarfs the difference between most quarterbacks.
What You're Actually Betting
A passing touchdown prop asks how many touchdown passes one quarterback throws in one game. Books post it as an over/under, almost always at 1.5, occasionally at 2.5 for an elite arm in a shootout or 0.5 for a backup in a rainstorm. Alt lines sit above and below.

If the mechanics of prop pricing are new to you, start with our guide to NFL player props and come back. This piece assumes you already know how to read a price and strip the vig out of one. What follows is what the market looks like underneath.
The Distribution Nobody Shows You
Here is every start from the 2024 and 2025 regular seasons in which a quarterback threw at least 20 passes. That's 1,021 games, pulled from the public nflverse play-by-play data:
| Passing TDs | Share of starts |
|---|
| 0 | 21.1% |
| 1 | 33.0% |
| 2 | 28.2% |
| 3 | 11.7% |
| 4 | 4.8% |
| 5+ | 1.3% |
The row that should stop you is 0 touchdowns: 21.1%. Better than one start in five, a starting NFL quarterback throws zero touchdown passes. Any starting quarterback, including the best ones. That is not a bad-quarterback rate; it's the base rate of the sport. Every time you take an over here, you are accepting roughly a one-in-five chance the bet is dead before it has a pulse.
Add the top three rows and you get the number that prices this market: over 1.5 passing touchdowns hits 45.9% of the time. Under is the majority side. A coin flip it is not.
It's A Poisson Market, And That Explains Everything
Rare, roughly independent events arriving at a stable rate produce a Poisson distribution. It's the same curve that describes how many customers walk into a store in an hour. Passing touchdowns fit it almost eerily well:
| Passing TDs | Actual (2024–25) | Poisson at 1.50 |
|---|
| 0 | 21.1% | 22.3% |
| 1 | 33.0% | 33.5% |
| 2 | 28.2% | 25.1% |
| 3 | 11.7% | 12.5% |
| 4 | 4.8% | 4.7% |
| 5+ | 1.3% | 1.9% |
Four of the six rows land within a single percentage point of a textbook curve fed nothing but the league average. That model has never watched a football game. It doesn't know who Josh Allen is. It goes 4-for-6 anyway.
The gap worth studying is the 2-touchdown row: 28.2% actual against 25.1% predicted. Real quarterbacks throw exactly two a little more often than pure randomness says they should, because offenses aren't truly random. They cluster around a game plan and a script. But that 3-point bulge is the entire measurable footprint of NFL coaching, scheme, and quarterback talent on this distribution. Everything else is noise wearing a jersey.
This is the part I'd underline. When a market's payoff structure sits that close to a random process, your edge cannot come from being smarter about football. It has to come from the price.
Why The Juice Is Worse Here Than On Passing Yards
Now the two facts collide, and the market's whole design falls out of it.
A passing yards prop is a continuous market. The book wants a coin flip, so it hunts for the number that splits the outcome in half (246.5, 247.5, 248.5) and tunes it in half-yard steps until both sides sit near -110. The line does the work, and the juice stays modest.
Passing touchdowns can't do that. The outcome is a whole number. There is no 1.7. The book has exactly two usable lines, and look at what sits between them:
- Over 1.5 → 45.9% → fair price about +118
- Over 2.5 → 17.7% → fair price about +464
One notch on the line is a 346-cent move in fair price. No half-step, no fine adjustment, nothing in between. So when a book thinks a quarterback is a shade better than baseline, it cannot nudge the line. The only place that opinion can go is into the price.
That has two consequences, and the second one is the useful one.
First, the hold on this market lives entirely in the juice, which is why passing touchdown props rank among the more expensive prices on the prop menu. You pay the book's whole opinion in one number.
Second, and this is the opening: every disagreement between two sportsbooks also shows up as price, not line. On passing yards, two books that disagree post 246.5 and 248.5, and you have to decide which number you even want. On passing touchdowns, DraftKings, FanDuel, BetMGM 🎁 and Caesars 🎁 all post the same 1.5 and simply charge differently for it. Same event, same threshold, four prices, and you take the best one. Line shopping is never more mechanical than it is here, and skipping it means donating an edge on a bet you were making anyway.

Worked Example: Pricing An Over 1.5
Say a book posts Over 1.5 passing touchdowns on a starting quarterback and you're deciding whether to take it. The workflow runs three steps, and none of them start with the quarterback.
- Anchor to the baseline. Fair price at league average is +118. That's your zero point. Anything shorter than +118 means the market is telling you this quarterback is above average, this game is above average, or the book is charging you for the privilege.
- Ask what the price implies. If a book hangs +100, that implies a 50% chance. Against a 45.9% baseline, you're being asked to believe this quarterback's true rate runs about four points better than the average NFL starter, before any vig. Sometimes that's obviously fine. Often it isn't.
- Compare the books, not your gut. Because every book uses the same 1.5, the best available number is a straight read across. A 15-cent gap between two books on an identical bet is pure edge, collected for free. De-vig the two-sided market to see what the field really thinks, then take the outlier. Our live NFL passing touchdowns odds screen puts every book on one page, and the DraftKings promo and FanDuel promo pages are worth a look if you need a second or third account to shop with.
Do this and you'll notice something uncomfortable. The honest fair price is +118, and the over is frequently offered at less than that. The market's default state on this prop is "the over is a little expensive." That's a stance worth carrying into every card.
The Signal: Red-Zone Pass Rate
If the quarterback's name barely moves the distribution, what does? Field position and play calling.
Across all 272 games of the 2025 regular season, 71.1% of passing touchdowns were thrown from inside the 20-yard line. 47.7% came from inside the 10. Nearly a third, 29.5%, came from inside the 5. A passing touchdown prop is not a bet on a 60-yard bomb. It's a bet on what a coordinator calls on 2nd-and-goal from the 4.
Which makes red-zone pass rate the number to check. Here's the 2025 spread:
| 2025 Red-Zone Pass Rate | Team |
|---|
| 69.2% | Arizona |
| 61.3% | Minnesota |
| 60.9% | Cincinnati |
| 51.2% | League average |
| 43.2% | Seattle |
| 41.6% | Philadelphia |
| 40.1% | Baltimore / Washington |
Arizona threw it on 69.2% of its red-zone snaps. Baltimore and Washington threw it on 40.1%. That's a 29-point gap in how often a quarterback is even handed the chance to throw a touchdown from the only place most of them get thrown, and it towers over the gap between most quarterbacks' talent.
One honest caveat, because it matters: Arizona's number isn't pure scheme. Teams that trail throw more, in the red zone and everywhere else, so a high red-zone pass rate is partly a confession about the defense. That's exactly why you read it next to the game lines. A pass-heavy red-zone team getting points is a different bet than a pass-heavy red-zone team laying a touchdown, even though the prop looks identical.
Baltimore's 40.1% is the mirror image: a team that hands the ball to its quarterback near the goal line and asks him to run it in himself. Those touchdowns count for the offense. They do nothing for the passing prop. That's the trap in one sentence. A great quarterback on a team that runs it in from the 3 is a worse passing touchdown bet than a mediocre one on a team that throws it.
How Much Does The Quarterback Actually Matter?
Some. Here are the 32 quarterbacks with at least 14 starts across 2024–25, sorted by how often they cleared 1.5:
| Quarterback | Starts | Over 1.5 rate | TDs/game |
|---|
| Joe Burrow | 24 | 75.0% | 2.46 |
| Matthew Stafford | 32 | 65.6% | 2.03 |
| Josh Allen | 28 | 64.3% | 1.75 |
| Jared Goff | 32 | 62.5% | 2.06 |
| Baker Mayfield | 32 | 62.5% | 2.03 |
| Jacoby Brissett | 17 | 58.8% | 1.47 |
| League Baseline | 1,021 | 45.9% | 1.50 |
| Geno Smith | 30 | 30.0% | 1.33 |
| Kyler Murray | 22 | 27.3% | 1.23 |
| Cam Ward | 16 | 25.0% | 0.94 |
| Spencer Rattler | 15 | 13.3% | 0.80 |
So the name isn't nothing. A 75% Burrow and a 13% Rattler are not the same bet. But look at the sample sizes. Twenty-four games is a season and a half. A 75% rate over 24 starts is not a 75% forecast; it's a noisy estimate that regresses hard toward 1.50. The honest read is "meaningfully above baseline," and you should distrust any price that treats it as more precise than that.
Now, the quarterback I promised you. Jacoby Brissett cleared 1.5 in 58.8% of his starts while averaging 1.47 touchdowns per game, which is below the league average. He was a top-eight over-1.5 quarterback and a below-average touchdown passer at the same time.
That isn't a paradox. It's the Poisson curve doing exactly what Poisson curves do. The prop doesn't pay on the average; it pays on a threshold. A quarterback who throws two a lot and zero rarely beats 1.5 more often than a boom-bust arm with a gaudier mean who alternates four-touchdown games with duds. Reading the season-long touchdown total is the single most common way people misprice this market. Ask how often he clears two, not how many he averages. Those are different questions, and only one of them is on your bet slip.
What This Market Punishes
- Betting The Average Instead Of The Threshold. See Brissett. The mean and the over-1.5 rate are different numbers, and the book only pays one of them.
- Betting The Narrative. As Eytan put it on Eytan's Essentials, a trend-of-the-day stat is "the stuff that just makes [Ben Rasa's] head explode," right before he explained why he wasn't touching a spread because of one. A quarterback throwing two touchdowns in three straight games is a Poisson process doing normal Poisson things, not a signal.
- Ignoring The Injury Tail. On our OS Live props show in October 2024, we walked through a card that needed two passing touchdowns from Jayden Daniels to hit 25x. Daniels got hurt early and never came back. No red-zone read survives an ankle, and a two-touchdown requirement is a bet that one specific human plays a full, healthy game. Hedging out of that spot is a legitimate choice, but be clear about what it is: you're paying a second helping of vig to buy down variance, which surrenders expected value in exchange for sleep. That's a risk-tolerance decision, not a profit strategy.
- Chasing The 2.5. That +464 looks gorgeous. It hits 17.7% of the time. Books know the number is pretty; that's why they hang it.
- Taking The First Price You See. On a market where every book posts an identical 1.5, refusing to shop means handing back the one edge that requires no handicapping at all.
Frequently Asked Questions
What is the average number of passing touchdowns in an NFL game?
A starting quarterback (20+ attempts) averaged 1.50 passing touchdowns per start across the 2024 and 2025 regular seasons: 1.49 and 1.51 respectively, over 1,021 starts.
How often does over 1.5 passing touchdowns hit?
45.9% of the time at league baseline, which makes the fair price roughly +118. Under 1.5 is the majority side at 54.1%.
Why are passing touchdown props so juiced?
Because the outcome is a whole number, the book only has 1.5 and 2.5 to work with, and the fair price between them jumps from about +118 to about +464. It can't fine-tune the line the way it can on passing yards, so it fine-tunes the price instead. All of the book's adjustment lands in the juice.
What's the best stat for predicting passing touchdown props?
Red-zone pass rate. In 2025, 71.1% of passing touchdowns were thrown from inside the 20 and 47.7% from inside the 10, while team red-zone pass rate ranged from 69.2% down to 40.1%. That spread is bigger than the gap between most quarterbacks.
Are passing touchdown props better than anytime touchdown props?
They're different bets with different structures. Anytime touchdown props hinge on which individual gets the goal-line work; passing touchdowns hinge on whether the team throws it there at all. Our anytime touchdown guide covers the other side of the same red-zone read.
Should I bet over 2.5 passing touchdowns?
Only at a price better than about +464, which is the honest baseline. Three-touchdown games happen 17.7% of the time. The payout is large because the event is rare, not because the bet is good.
The Number Was Never About The Quarterback
Two seasons, 1,021 starts, and the average never budged off 1.50. A curve that has never seen a football game predicts this market to within a point on most rows. The book can't move the line, so it moves the price. Nearly three-quarters of the touchdowns come from a patch of grass 20 yards deep, and whether your quarterback gets to throw from it is a decision his coordinator makes rather than one he earns.
None of that makes the market unbeatable. It means the market is beatable in a specific way, and handicapping the quarterback harder is not it. Anchor to +118. Ask whether the team throws inside the 10. Ask how often he clears two, not what he averages. Then take the best number on a line that every book in the country has already agreed on, because when everyone posts the same 1.5, the only thing left to win is the price.
