What Is the NBA Preseason and How to Bet on It

The NBA preseason is the only part of the season when bookmakers often have a poor read on what is happening on the court. Stars rest, reserves get 30 minutes, coaches experiment with lineups, and the results mean virtually nothing. For most bettors, that is a reason to skip these games. For those who understand the logic, it can create opportunities for value bets.

In this guide, we explain how the preseason works, how it differs from the regular season, which markets can be more profitable, and how to avoid the mistakes most beginners make.

What Is the NBA Preseason

The NBA preseason is a series of exhibition games played 2–3 weeks before the regular season begins, usually from early to mid-October. Each team plays between 4 and 6 games. The results do not affect the standings, playoffs, or official player statistics — this is purely a preparation period. The league does not require teams to play a specific number of games, but it does not allow more than six.

Why the Preseason Is Needed

• Testing the roster. Coaches evaluate rookies, reserves, and players on two-way contracts. Stars usually play 15–25 minutes, while bench players receive the most court time to prove their value.
• Working on tactics. Teams test new schemes, combinations, and lineups that would be too risky to experiment with during the regular season.
• Getting into shape. Players prepare for a demanding schedule after the offseason. Those returning from injuries receive controlled workloads.
• Commercial goals. Games at neutral and international venues help promote the NBA brand in new markets.

How the Preseason Differs From the Regular Season

During the regular season, each club plays 82 games and lineups are relatively stable. In the preseason, a coach can completely change the rotation from one game to the next: the leaders may play 20 minutes in one game and rest in the next. This creates opportunities for value bets because bookmaker lines often fail to reflect the true strength of the available lineups quickly enough.

Another important detail is that home-court advantage barely works in the preseason. Crowds are smaller, the atmosphere is different, and teams often play at neutral venues without genuine home support.

What to Bet On: Markets and Strategies

Positive Spread on Underdogs

This is the most statistically justified preseason strategy. Teams that made the playoffs the previous season usually protect their leaders. Teams that missed the postseason often give their players more minutes and take the games more seriously. Underdogs with a positive spread cover more often than in the regular season because the motivational imbalance can compensate for the difference in class.

Heavy Underdogs

Historically, this has been the most profitable category of preseason bets. Many games are essentially a coin flip, while bookmakers tend to overrate favorites. At odds of 3:1, hitting one out of every three games is enough to stay profitable over the long run.

Under Total

Scoring in the preseason is usually lower than in the regular season. Stars play limited minutes, reserves are less efficient offensively, and defensive systems are often not fully developed. The under is a reasonable default direction, especially when both teams traditionally play at a slow pace or when the game comes during a congested schedule.

Coaching Tendencies

Some coaches take the preseason seriously and experiment less often. Tom Thibodeau, for example, traditionally gives his players heavy workloads even in exhibition games. If you know that Team A's coach usually pushes the roster hard while Team B's coach openly treats the preseason as an experiment, that is an informational edge the bookmaker may not fully price into the line.

Quarter Betting

In the preseason, teams often play the first half with a lineup close to the regular rotation, while deep reserves finish the game. This can create value in second-half markets when players whose strength is underestimated by the bookmaker take the court.

How to Analyze NBA Preseason Games

Lineups and Star Minutes

This is factor No. 1. Find out who will rest, who will play 30 minutes, and who will play 10. This information is usually available in pregame reports, coaches' press conferences, and team social media. If Team A's leader is resting while Team B uses a full lineup, the favorite may not have as much of an edge as the line suggests.

Schedule and Fatigue

If a team is playing its second game in two days or has just returned from an international trip, it will definitely protect its leaders. Travel and time-zone changes can affect minute restrictions even more than tactical decisions by the coach.

Coach Behavior in the Preseason

Some coaches play to win, while others openly experiment. Track how each coach has historically approached the preseason — this information is available across several seasons. A coach who won 5 of 6 preseason games last year will most likely continue in the same direction.

Bench Form

Knowing a specific team's bench is your main advantage over the bookmaker. The line is built around the strength of the starting lineups, while preseason outcomes are often decided by rotation players. If you know Team A has a stronger bench than Team B, that can create value.

Rookies and Draft Picks

Rookies often receive extended minutes in the preseason, especially on teams that are not expected to contend for the title. If a high draft pick starts the game, it is a signal that the coach wants to evaluate him in competitive conditions, and the team may play more aggressively than the bookmaker expects.

Common Mistakes When Betting on the Preseason

• Betting on a favorite to win outright. Favorites regularly lose in the preseason because the result is not important to them. The odds are low and the risk is high, making this the least profitable direction.
• Using last season's statistics. Rosters change and motivation is different, so old data is almost useless. Focus on current lineup and minutes information.
• Betting large amounts. The preseason is the most unpredictable part of the season. Bankroll management matters more here than anywhere else. Bet no more than 50% of your bankroll on a single game.
• Ignoring lineup news. Whether a star starts or rests changes everything. A bet placed an hour before the game may turn out to be valuable or unprofitable depending on the latest information.
• Applying regular-season logic. Home/away factors, injuries, and motivation work differently when the result does not matter. Do not carry regular-season habits into the preseason.
