Coach Speak: The Single Biggest NFL Preseason Betting Edge

The Quick Answer

Preseason NFL should be treated as a different sport, because the single biggest edge has nothing to do with talent and everything to do with playing time. Coaches control it, coaches talk about it, and coaches sort into three types: honest, deceptive, and deceptively honest, the ones who lie to the media so predictably that the lie itself is the information. Markets swing violently on coach announcements and routinely swing the wrong amount, and nowhere is that more visible than on Kalshi, where thin preseason books are already posting prices like an 8-cent-wide market on Andy Reid's Chiefs. The full coach taxonomy, the joint-practice tell, and where the edge lives on Kalshi's markets are below.

Betting preseason NFL is nothing like the regular season.

Actually, you should consider treating it as a different sport entirely, because much of the info you may use to find an edge in the regular season is useless in August.

And this isn't because there won't be an imbalance of talent in many of the games you'll see starting with Thursday's Hall of Fame game, but because you'll have to figure out who's going to be on the field first before determining anything else.

Which is why anyone who plans on betting preseason football this summer should be paying very close attention to one very specific element of the game: coach speak.

The Three Kinds of Preseason Coaches

In the preseason there are honest coaches, deceptive coaches, and honestly deceptive coaches. Let me explain.

The honest coaches will tell you how they're going to use their players in a preseason game and they'll actually do it. A novel concept, I know, but they reliably do what they say they're going to, and there's a decent amount of those coaches in the league right now.

The deceptive coaches will say one thing and do the other with very little predictability week-to-week or season-to-season. Mike McDaniel was a perfect example, speaking to the media in unintelligible riddles and making it impossible to get your finger on the pulse of how he'd use his players in preseason games.

Then there's the most fascinating type of coach: the deceptively honest. The Andy Reid type. The Nick Sirianni. Reid will announce that his starters are playing a quarter, and every season in that game they play a single drive. When he says they'll play a half they never play more than a quarter. He blatantly lies to the media, but with such predictability that we don't actually need him to tell the truth.

Similarly, Nick Sirianni will play coy with the media suggesting he doesn't know if starters are going to see the field, but they never do. Even when he appears to be wrestling with the decision, they never play. Could that change this season? Sure. But it hasn't for years, and the same goes for Reid.

Why the Liars Are the Most Valuable

It might seem logical to rely on the honest coaches to find a betting edge while ignoring the others, but I'd argue the deceptively honest coaches are more valuable to us than any of the others.

Every year I've bet the preseason, the lines swing violently when a coach announces his plans for starters and backups, as they should. But oftentimes the moves are too extreme, or not extreme enough, based on what we know about how these coaches behave compared to what they say.

This is exactly where Kalshi gets interesting. The exchange already has winner markets live for next weekend's preseason slate, and the prices, as of 9:15 p.m. ET on August 5, 2026, tell you how raw these books are:

Settlement is simple: these markets settle on the final score the same night. And if you're coming from sportsbooks, Kalshi prices read directly as probabilities, so Seattle at 61-62 cents is roughly a 61% favorite, no vig math required. That Chiefs quote deserves a second look through the same lens: an 8-cent-wide book is the market's way of admitting it has no idea what Reid intends to do with his starters.

When the playing-time announcements come, thin books don't drift. They lurch, and they routinely lurch the wrong amount.

A sportsbook has a trading desk pricing the Reid discount into the line before you wake up. A thin event-contract book has whoever happens to be quoting it that morning. If you know that "a quarter" means one drive, you know which lurches to fade and which ones haven't gone far enough. And the Pavia market is worth dwelling on: that's not a derivative of the coach-speak edge. That is the coach-speak edge, listed as its own instrument.

How To Price the Reid Discount: A Worked Example

Take the live Kansas City number, 52-60 cents against the Rams. Sometime before kickoff, Reid will tell reporters his plan, and history says to apply the discount before the market does: "starters for a quarter" has meant one drive, "a half" has meant a quarter at most. So if Reid announces a half and the book lurches toward Kansas City on the assumption of real Mahomes minutes, the announcement moved the price further than the truth warrants, and the other side of the lurch is where the value sits. The number you're actually handicapping is backup-quarterback minutes, which is most of the game either way. The announcement didn't change the game; it changed the price. And the discount only stays tradable because it keeps getting graded against reality every August: write your read down before the announcement, then check it against the box score.

Joint Practices Tell You Who Plays

Joint practices can also paint a pretty clear picture for us. Now more than ever, coaches are using joint practices to prepare their starters for the regular season while playing mostly backups and roster-bubble players in the actual games. But when starting units underperform in joint practices, many coaches are more inclined to get them on the field for the real thing. They're usually pretty upfront about their displeasure, too, and in my experience when that happens you know the starters are going to be on the field.

This is also the layer where doing your homework daily pays off, because the signal shows up in beat-writer reports days before it shows up in a price. Our NFL training camp hub tracks exactly these reports, every morning, from the people standing on the sideline.

The Catch: Playing Time Depends on the First Two Drives

Here's the catch: how long a coach decides to play his starters almost always depends on how they perform early in the game. If a starting unit that struggled all week in practice and in joint sessions methodically drives down the field for a touchdown on their first possession, that may be enough for a coach to sit them for the rest of the game.

Conversely, if they're having no success and go three-and-out twice to start a game, they may play an entire half. These are the types of things you want to figure out ahead of time, and that all comes down to understanding how each coach evaluates his players and utilizes the preseason.

Bet the First Quarter, Not the Game

It's also why betting first-quarter or first-half lines in the preseason can be profitable: if you're confident you know the playing time of the starters, but have zero confidence in how the team will perform once it's replaced with second- and third-string players, betting the full game could work against you.

The same logic applies on Kalshi, with one wrinkle worth knowing: event-contract menus fill out close to game day. The winner markets go up first, and the deeper game boards populate as kickoff approaches, so the disciplined play is to form your playing-time read early, from the coach's history and the week of practice reports, and then act when the market you actually want appears. The read comes first; the instrument shows up later. If you'd rather shop the same game across sportsbooks while you wait, the live odds screen shows every major book's preseason number side by side.

Now, none of this is to say you can't find legitimate edges betting preseason games where none of the starters from either team ever see the field, because you absolutely can. Preseason games largely come down to which backup quarterback is more competent, or in fairness, is the least bad. But there's a real advantage to understanding coaching tendencies down to what they say to the media, what they've done in the past, and what has transpired in recent practices that might make them change their usually predictable course.

The Preseason Cheat Sheet

Everything above, on one card:

At the end of the day, betting preseason football is quite the enjoyable endeavor, where for three weeks you're playing a psychologist who tries to get inside the heads of coaches you've never spoken to before.

Also, who the hell wants to wait until September to bet an NFL game?
