The Boston Celtics have ascended to the number one spot in the latest NBA power rankings, fueled by a flawless week and a league-best five-game winning streak. Their 98-93 road victory over the Toronto Raptors on November 11, 2026, sealed a perfect 5-0 stretch that showed both their offensive firepower and defensive resilience.

This climb to the summit comes as injuries continue to reshape the league landscape, impacting contenders like the Philadelphia 76ers who have slid down the order. The Celtics, however, have handled the early season chaos with remarkable consistency, building momentum with each impressive performance.

The Celtics' claim to the top spot is built on overwhelming recent results and statistical dominance. Their net rating over the past week has been among the league's elite, a direct product of their performances. The week was highlighted by a commanding 123-101 demolition of the Philadelphia 76ers on November 10, a statement win against a conference rival.

Head coach Joe Mazzulla has his team executing on both ends of the floor. Offensive sets are generating high-percentage looks, while the defensive rotations have been sharp and communicative. Key players are stepping up, with the team's core contributors delivering efficient scoring, playmaking, and rebounding night after night. This balanced attack makes them a nightmare matchup for any opponent.

Looking at the last five games reveals a team in peak form. The winning run started with a 109-102 home win against the Milwaukee Bucks on November 4. They followed that with a dominant 119-80 victory over the Charlotte Hornets on November 6, then another 117-97 win against those same Bucks on November 8. The back-to-back wins against Philadelphia and Toronto capped off the perfect week.

This stretch has stays as the team to beat in the Eastern Conference. It's not only that they're winning, but how they're doing it. Blowout victories demonstrate their ability to put games away early, while gritty wins like the one in Toronto show they can execute in clutch moments.

Maintaining this level of play is the immediate challenge. The NBA season is a marathon, and avoiding complacency after a hot start is vital. Their next test is a high-profile home matchup against the Dallas Mavericks on November 15, 2026. The Mavericks present a unique challenge with their dynamic backcourt, offering a great measuring stick for Boston's perimeter defense.

Also, the injury wave sweeping the league is a constant reminder of how quickly fortunes can change. While the Celtics have been healthy, staying that way is a priority. The team's depth will be tested over the long season, especially during back-to-backs and a crowded schedule. Managing minutes and keeping players fresh for a potential deep playoff run is a delicate balancing act for the coaching staff.

The power rankings shift shows a volatile start to the season across the NBA. Several presumed contenders have struggled out of the gate, while teams like the Celtics have seized the opportunity to establish early dominance. The absence of stars like Stephen Curry and rising talents like Caleb Wilson due to injury has created openings for other teams to rise.

For Boston, the focus remains internal. The message from the locker room will be about daily improvement and not getting caught up in early-November rankings. But there's no denying the statement they've made. A 5-0 run sends a clear message to the rest of the league: the Boston Celtics are the current standard.
