Preseason NFL betting isn't for degenerates: Why there is value and how to find it

· Yahoo Sports

The NFL offseason is finally over. Training camps are open, the Hall of Fame Game kicked off with a memorable 33-30 win for the Carolina Panthers over the Arizona Cardinals and the same question that comes back every summer is here: Is it actually worth betting preseason football?

You've heard the take everywhere: Preseason is for degenerates. The starters don't play, the football is ugly — just wait three weeks for the real thing. All of that is true. And it's the exact reason these games can be profitable for bettors.

Here's the truth: by Week 1 of the regular season, the books are a machine. Millions of dollars and years of data grind every number down to the half-point. In August, that machine is guessing. The preseason isn't worse football to bet, it's softer football to bet. If you know what you're actually looking at, that softness is the edge.

Here's how I go about betting the preseason and why there is value.

A regular season line is built on talent, and the books know talent. A preseason line is built on that same talent, but for a roster that's going to play a dozen snaps and then hand the game to guys you've never heard of fighting for their spot on a team.

That's the problem for oddsmakers: They can price the Kansas City Chiefs, but can't price whether Andy Reid wants to win a meaningless game or pull his starters after one series. Talent is in the number, but intent isn't — and that's what decides preseason games.

You can see this softness in two places.

First, the books don't even agree with each other. In the regular season, every shop hangs basically the same number. In August, you'll find the same game a full point apart across books, with the juice swinging from -105 to -120 on the same side.

Second, the limits drop. Books cut how much you can bet on preseason games because they know they're exposed, and lower limits mean the numbers move on modest action.

Both of those signs are the market telling you it isn't sure. Shop your number and get down early. Nowhere in football does line shopping matter more.

The preseason is the only time in sports you can bet on a coach who's trying to win against a coach who flat out isn't. Some coaches use August to set a tone and win over a locker room. Others would rather go 0-3 than lose anyone to injury. Figure out which is which, and you're already ahead of the number.

This may feel too obvious and baked in, but historically the records back it up.

John Harbaugh built his name as a preseason killer, going 38-22-1 against the spread for his career, because his teams competed when the other side mailed it in. Dan Quinn is the opposite, a near automatic fade at 6-18 ATS, the worst mark of any coach with a real sample. And a whole tier of coaches — the Sean McVay and Nick Sirianni types — barely play their starters and will tell you the final score was the least important thing that happened.

Even Bill Belichick's teams were only about .500 ATS in August because winning these games straight up doesn't mean covering once the market prices the effort in.

However, the obvious edges are already gone. Harbaugh's the poster child: over 60% for his career, but 0-6 ATS the last two years once everyone caught on. From coaches to knowing snap counts, the edge hides in the uncertainty of these unique games.

The coach can tell you how hard a team will try to win, but the depth chart tells you who's actually out there. And nobody's out there for long anymore. The average starting quarterback threw just 10.1 passes all of last preseason, down from 14.3 in 2021. Ten Week 1 starters didn't throw a single pass across three games. The starter is a cameo now, if he shows up at all.

So the games get decided by the QB2s and QB3s, which makes the backup quarterback the cleanest read in August. A team with a steady veteran backup, a Cooper Rush-type who's seen every coverage, against a team handing it to a sixth-round rookie and a camp arm is a real edge. And it only grows as the quarters roll and the rosters get younger. Treat these guys like starting pitchers in baseball. The name taking the snaps is the biggest number in the game, and it changes by the drive. That's why playing time news is the most valuable thing you can research and learn this month.

A coordinator tips his plan in a presser. A beat writer posts the rep split from that morning's practice. The line moves on it before the casual bettor ever notices. Follow local writers directly — not aggregators — read the report and get your bet down before the number catches up.

There are three preseason games, and each one plays differently. Treating them the same is how people get buried.

Week 1 is deep reserve football. Pure evaluation, about as random as it gets and the spot where a team with real depth can steal one. Lean on coaching intent here, not talent.

Week 2 is the dress rehearsal. Most starters get their longest look of the summer, so it plays closest to real football, and coaching motivation matters most.

Week 3 is the finale, and it splits the league in half. Contenders wrap their key guys in bubble wrap and empty the bench. Teams with jobs still open keep competing. Knowing which side a team is on beats any power rating you can pull up.

None of these are locks. Anybody selling them as locks is selling you something. But start with the oldest edge in the book: underdogs.

Preseason dogs have covered somewhere around 52% to 54% for as long as anyone has tracked it — and it isn't luck.

A study going back to the 1990s found the reason plainly: the books set preseason spreads too high. Backups keep games close, favorites don't pull away and the number never fully adjusts for it.

From there, it sharpens:

  • Small road 'dogs (2.5 points or fewer) have gone roughly 75-38 ATS over the last decade, north of 66%. Nobody respects the road team in August.

  • Short 'dogs in general. Getting 1 to 3 points, underdogs have hit around 60% since 2015. Scores stay compressed, and blowouts are the exception.

  • Totals settle around 37. Closing totals of 37 or lower have gone over close to 60% of the time. Set above 37, they've hit the under around 56%, and that result holds across separate data sets. Ignore the "preseason unders hit 80%" stuff — it's marketing with no sample size behind it.

  • The under is a Week 3 bet, not a blanket one. Early on, there's no totals edge. It shows up late: on high totals in the final week or two, the under has hit closer to 60%.

  • Momentum carries. Teams off a 20-point beatdown the week before have gone 17-10-2 ATS the next time out. It's a real edge, the book just makes you pay a little for it.

Preseason spreads sit tight, usually 1 to 2.5 points, and totals sit low. That scarcity sets up the one structural edge in these games: the teaser.

NFL margins cluster around 3 and 7 because points come in field goals and touchdowns. A six-point teaser buys your number through both. The classic legs are a short 'dog (around +1.5 to +2.5) teased up through the 3 and the 7, or a mid-size favorite (-7.5 to -8.5) teased down through the 7 and the 3.

Those legs have cashed around 75% long term, and low-scoring games only help. Fewer scores mean a final margin is more likely to land on a key number instead of flying past it.

Here's the part most preseason articles skip: the teaser is only a bet at the right price. At -130 or -135 — where most books now price teasers — the edge is gone. Find a book still hanging -120, or pass.

One honest caveat: that 75% is a regular-season figure. The preseason logic holds, but there's no clean preseason-only sample. Treat it like an edge you believe in, not a lock you've proven.

Two things make this preseason unusually live.

First, the coaching carousel. Ten teams changed head coaches this offseason, and six handed the job to a first timer. A first-time head coach is auditioning for the building, installing a new scheme and needs live reps to see if it works. That usually means starters on the field longer and a real effort to win.

The market has no read on these guys yet, so their intent is a guess to price. That's your opening.

But the bigger tell is who moved. John Harbaugh — arguably the best preseason coach ever — took over the New York Giants, a team that spent the last few years with Brian Daboll and his 1-8 preseason ATS mark. New York went from maybe the worst preseason coach in the league to maybe the best in a single hire, and the market usually takes a beat to re-price that.

On the other side, Mike McCarthy landed in Pittsburgh. He's a career .500 preseason coach who plays his starters a series and pulls them. Don't pay for Steelers preseason wins that aren't coming.

Second, keep an eye on the open quarterback jobs, because those are the games where starters actually play. Cleveland is the headliner: a real competition with Deshaun Watson working back from a second Achilles surgery and second-year player Shedeur Sanders, under a first-year staff that has to sort it out live.

When a job is that open, the reps are real and the games matter. Arizona, Minnesota, and Las Vegas are sorting out QB situations as well. The flip side is just as useful: when the job is settled, the starter is a cameo. Fade the inflated brand name and move on.
