Boston Celtics 2025-26 NBA Betting Lines
Last year was a bitter disappointment for Boston Celtics fans and the gamblers who had high expectations for a repeat NBA championship. The news did not get better in the summer of 2025 with an offseason that was, to be charitable, underwhelming. Boston trimmed key talent off its roster and did not bring enough quality in return. Gamblers have taken notice and are fleeing the Celtics on the futures market for the season ahead. In 2024-25, Boston finished with the third-best record in the NBA but was in the red against the oddsmakers after being one of the most profitable teams on the board in the previous season. Thus, it was fair for gamblers to believe that the Celtics were suffering from a championship hangover. And things may get worse before they get better.
NBA Betting Lines
Team Overview
The Boston Celtics' final regular season record was 61-21 straight up, 38-43-1 against the spread, and 37-44-1 over/under the total. Boston was second in the Eastern Conference playoff standings, three games behind the Cleveland Cavaliers.
Boston's NBA metrics were 8th for scoring offense, 19th for field goal percentage, 10th for 3-point field goal percentage, 6th for free throw percentage, and 8th for offensive rebounding. On defense, the Celtics' metrics were 2nd for scoring defense, 2nd for field goal percentage permitted, 3rd for 3-point field goal percentage allowed, and 13th for defensive rebounding.
Boston’s 2024 NBA championship hangover never ended. The Celtics were eliminated in the second round of the 2025 NBA Playoffs in six games by the New York Knicks. Game 6 was a 119-81 debacle in which Boston clearly checked out.

Off-Season Moves for 2025-26
Key additions: Anfernee Simons, Georges Niang, Luka Garza, Hugo González, Josh Minott
Key subtractions: Kristaps Porzingis, Jrue Holiday, Luke Kornet
The Celtics entered the summer knowing they needed to get under the second level, and they are well on their way to getting it done. It cost them Porzingis and Jrue Holiday, a pair of impactful veterans. Luke Kornet left for more money from the San Antonio Spurs, too. The return for Porzingis and Holiday — Anfernee Simons and Niang — was as underwhelming as expected for what amounted to a salary dump.
They drafted Hugo González, whose work showed in the summer league, and they added a pair of under-utilized former Minnesota Timberwolves, Luka Garza and Josh Minott. None of it will steal headlines, but all of it was necessary, and they came out on the other side of it about as flexible as they could. In the end, following Tatum's injury, everything Boston does is with championship contention in 2027 in mind.
The upside is the Celtics managed to balance their books without giving up any future first-round picks, getting under the second level with a plausible path to avoiding the tax altogether in a gap year following Jayson Tatum's Achilles rupture. The downside is Boston shed a massive amount of talent, including everyone taller than 6-foot-8 who played at least 13 minutes in the 2025 playoffs. The Celtics will be challenged to replenish their frontcourt depth and, crucially, the versatility lost with Al Horford and Kristaps Porzingis.
Key Players
SF Jayson Tatum was the third overall pick of the 2017 NBA Draft out of Duke. Tatum is a 6-time NBA All-Star and was on the ACC All-Freshman team for Duke. Also, he was a McDonald’s All-American and Gatorade National Player of the Year. This past season, Tatum averaged 26.8 points and 8.7 rebounds per contest. Tatum is a 2025 NBA All-Star. Tatum is recovering from an Achilles tear.
SG Jaylen Brown was the third overall pick of the 2016 NBA Draft out of California. He is a 4-time NBA All-Star and was the Pac-12 Freshman of the Year at Cal. Brown was a McDonald’s All-American. Brown is a 2025 NBA All-Star. He averaged 22.2 points and 5.8 rebounds per game in 2024-25.
Head Coach
Head coach Joe Mazzulla took over on an interim basis for the 2022-23 season and has proven to be the right man for the job. He led the Celtics to the 2024 NBA championship. He has a career record of 182-64.

Boston Celtics History
The Boston Celtics continually vie with the Los Angeles Lakers for the honor of being the most successful team in the history of the NBA. Boston has won 18 NBA championships, and the Celtics were one of the greatest dynasties the sports world has ever seen from the late 1950s until the late 1960s. The Celtics won 11 NBA titles in 13 years as Bill Russell established himself as one of the greatest players in the league's history.
Bob Cousy, KC Jones, John Havlicek, and Sam Jones were all elected to the NBA Hall of Fame for their contributions during this stretch.
Boston won two titles in the 1970s with Dave Cowens and Jo Jo White as the stars and the help of Havlicek and future coaches Paul Silas and Don Nelson. The next true Celtics dynasty wasn’t until the 1980s when Larry Legend became a household name.
Larry Bird was instrumental in taking the Celtics to the NBA Finals five times in seven years, and Boston won three championships before Bird’s back problems became too much. Kevin McHale and Robert Parish were also difference-makers on this team.
The 1990s were largely a down decade for this franchise as M.L. Carr and Rick Pitino failed to lead this team to the playoffs. However, the Celtics won their 17th NBA title in 2008, with Paul Pierce, Kevin Garnett, and Ray Allen all playing big roles.
