Expected score: Boston Celtics 92-86 Chicago Bulls
The Boston Celtics host the Chicago Bulls in an NBA season opener on 26 October 2026. Both teams arrive from the Las Vegas Summer League, where they faced competitive rosters and mixed results. The Celtics showed more consistency across their four outings, while the Bulls struggled defensively despite moments of offensive promise. This matchup offers an early test of regular-season readiness.
Team form
Boston Celtics
Boston went 2-2 in Summer League play, scoring 89.0 points per game while conceding the same average. They beat Sacramento 82-76 and Charlotte 87-75, but lost to Orlando 97-103 and Atlanta 90-102. The wins came against teams they controlled the tempo against; the losses suggest vulnerability when opponents dictated pace. Their offensive consistency—staying near 89 points across all four games—hints at a structured system, though the defensive lapses against Atlanta and Orlando warrant attention.
Chicago Bulls
Chicago finished 1-4 in Summer League action, averaging 86.2 points scored against 93.8 conceded. Their sole win came 99-87 over Washington, but they fell to Cleveland 91-100, Los Angeles 82-105, Utah 63-80, and Memphis 96-97. The 63-point outing against Utah was particularly concerning, suggesting they can collapse offensively under pressure. Defensively, they leaked points consistently, conceding over 90 in four of five games. The loss to Memphis by one point showed they can compete, but the pattern of defensive breakdowns is troubling.
Head-to-head
No prior meetings between these teams in the available record.
Key factors
Boston's offensive structure and balanced scoring should trouble Chicago's porous defence. The Celtics' ability to stay near 89 points even in losses indicates a system that functions regardless of opponent—an advantage when facing a Bulls team that has conceded 93.8 per game. Chicago's offensive inconsistency is the deeper concern; they managed only 86.2 per game and showed they can fall apart entirely, as evidenced by the Utah collapse. If the Bulls can avoid a defensive meltdown and maintain offensive rhythm similar to their Washington win, they have a path to compete. Boston's discipline and consistency, however, should prevail in a regular-season environment where structure matters more than Summer League improvisation.
Prediction
The Celtics enter as clear favourites. Their Summer League form, while not dominant, was steadier than Chicago's. Boston conceded 89 per game—respectable for a preseason setting—while the Bulls allowed 93.8, a gap that compounds over 48 minutes. Offensively, Boston's consistency suggests they will score in the low 90s regardless of matchup, and Chicago's defence has not shown the ability to hold opponents below that mark. The Bulls' one-point loss to Memphis and narrow win over Washington indicate they can compete in close games, but their four defeats and defensive vulnerabilities make them unlikely to overcome a Celtics team that has won more convincingly and shown better structural balance.
Boston should win this opener. The Celtics' offensive consistency and defensive solidity, relative to Chicago's defensive struggles, give them a clear edge. Expect a Celtics victory in a game where Boston controls pace and limits Chicago's scoring opportunities. The Bulls will need a near-perfect offensive performance and uncharacteristic defensive discipline to pull off an upset.
