In the '80s, at the Resorts, you'd stand at a bar and a guy would say "I'll give you three-to-one that Shaq scores 40 tonight." You'd shake hands. The bet was on. Nothing written down. The honor system held because money moved locally and slowly.
Now DraftKings has 247 prop bets for a single NFL game. Player passing yards, rushing yards, receptions, first touchdown scorer, total touchdowns, alternate totals, anytime touchdown, same-game parlays with prop stacking. The granularity is complete. The board has fractured into thousands of micro-markets, each with juice, each with a house edge.
Player Props
A player prop is a bet on an individual player's performance: "Will Josh Allen throw over 2.5 TDs tonight?" The sportsbook sets a line. It's usually sharp. Allen throws 2.2 TDs per game on average, so 2.5 is asking for above-average performance. The book prices it at -115 (you risk 115 to win 100) because the probability is slightly under 50 percent.
The advantage to the book is that player performance is less volatile than team outcomes. An NFL team might lose in a blowout (team props get hammered) or win in overtime (team props vary wildly). A single player's performance is more predictable. Allen will throw 2, 3, or 4 TDs most nights. He won't throw 8. This stability lets the book price props tightly.
For bettors, player props are seductive because they feel like skill plays. You watch Allen play weekly. You have opinions on his matchups. You feel like you know something. The book feels the same. They shade the line slightly in their favor, and the 200 people who think they know Allen's prop value split the difference. There's no real edge in following box scores and guessing pass completions.
Team Props
Team props measure outcomes: "Will the total exceed 45?" or "Will the favorite cover -4?" These are market-level bets. Everyone's making them. The liquidity is massive. A -4 point spread at DraftKings and Bet365 will be nearly identical because there's huge volume and sharp money arcing between books.
Team props are the backbone of sports betting. They're also where the market is most efficient. The line moves based on sharp action. Public money piles on favorites. The line adjusts quickly. After two hours of trading, the -4 line is probably exactly where it should be given all available information.
Betting team props against the market is a long-term losing proposition for most people. The book's edge on team totals is roughly 4.5 percent (the vig). You need a 5 percent edge to break even after the vig. Most bettors don't have that edge. They're guessing.
Novelty Props
Now we get to what I actually find interesting, which is the novelty stuff. "Will Mahomes' hair be longer at halftime than kickoff?" or "Will the referee wear a striped shirt" (always yes, but people bet it anyway). These bets are designed to pull casual players into the sportsbook. They're also where the book's edge is wildest.
On a novelty prop like "Which team's kicker will make a longer field goal," the book has maybe 3 percent of the information the player has (they watch football; the book has no special knowledge). But the vig is still 4.5 percent. You need to be 7.5 percent better than random to break even. Novelty props are designed to look fun and fail silently.
I saw a prop at the Borgata once: "Will Jon Bon Jovi attend the Super Bowl?" This was a real line. Neither team was from New Jersey. Jon Bon Jovi has no connection. The book set it at -115 on "yes" based purely on the narrative that he's a sports guy. People bet it. Most people lost. The book made 4.5 percent on a completely random outcome.
The Volume Explosion
In the '80s, you made one bet. Maybe two. Now you can make 247 bets on a single game. The entry point is 1 dollar. The friction is zero. You can parlay five props together and get 10-to-1 odds on an outcome that has maybe a 5 percent chance. You feel like you understand gambling when really you're making 50-to-1 shots with negative expected value.
The board I mentioned at the Resorts had maybe 20 bets available per game. You had to talk to a person. You had to do the mental work of comparing your estimate to the price. Now you have an app. The friction is gone. The volume has exploded. The total amount Americans are losing to prop bets has grown from maybe 100 million dollars annually in the late 2010s to several billion now.
What Separates Them
Player props feel like you're betting on a person (you think Mahomes will throw 3 TDs). Team props feel like you're betting on a game (the total will exceed 45). Novelty props feel like you're playing a game (guess this random thing). In reality, they're all the same: you're guessing an outcome, the book is taking a small edge on every guess, and over 100 guesses, the edge becomes your loss.
I remember talking to a guy at the bar in 1987. He said: "The best bet is the one you don't make." Then prop betting was slow and hard. You needed discipline. Now it's fast and easy. The boardwalk's almost empty these days anyway. The action moved to phones. The discipline moved out of the equation.
