NBA offseason power rankings: Thunder hold steady at the top, 76ers make the biggest climb in the summer tier picture

Free agency is not finished, but the NBA offseason picture is beginning to solidify anyway. In an edition of summer NBA power rankings published July 15, the top of the board is anchored by the Oklahoma City Thunder, while Philadelphia’s 76ers are highlighted as one of the bigger “climbers” after their offseason moves. The rankings also keep a close eye on the Knicks and Spurs, asking a simple question beneath the numbers: who has actually gained ground since the season ended, and who is still waiting for something to click?

The ranking structure matters as much as the order. The author frames the league in “tiers,” with the first tier limited to the top four teams as “true title contenders,” and teams ranked roughly five through ten treated as a second circle of contenders that require things to go right. That approach is particularly relevant in July, when rosters can still change and chemistry, health, and fit often have not been fully tested. It is also a reminder that summer rankings are projections, not verdicts.

Within that framework, the Thunder are placed in the top three, reflecting the view that their foundation and ongoing development have them positioned as a baseline elite team rather than a one-off jump. That matters for the title conversation because the league’s top tier typically requires both high-end talent and reliable creation of offense and defense in postseason conditions. Even as the offseason churn continues, a team that stays near the top of power rankings is benefiting from that kind of structural stability.

Philadelphia’s climb is the other headline inside the piece. The author explicitly asks how far the 76ers have risen after their offseason and treats their movement as meaningful enough to stand out within the summer tier picture. The underlying implication is that Philadelphia’s roster construction and matchup readiness have improved enough to move them closer to the league’s upper echelon, even if the ranking still lives in that “if” zone that comes with July projections.

The Knicks and Spurs are both referenced as teams the rankings are “measuring” in terms of offseason gains. For New York, the point is that the organization is not operating in a vacuum. If the Knicks have added enough to turn late-season performance into a more consistent playoff identity, they can be seen as moving within the second circle. For San Antonio, the question is whether the Spurs’ offseason changes shift them from rebuilding momentum to a more credible postseason path, at least in the ranking imagination.

One challenge of any offseason power rankings is that a lot of the “why” depends on assumptions that have not been proven in games. Fit is real, but it is also difficult to validate in practice alone, and postseason style can expose weaknesses that a summer roster looks fine hiding. The author’s tier language implicitly acknowledges this, positioning the rankings as an early take on what the league may look like once rosters settle.

Still, summer power rankings have a practical function. They offer a concise map of how league observers are weighing roster changes relative to playoff outcomes. A team climbing the list generally indicates that analysts see a step toward contention, not just another incremental offseason. A team staying put at the top indicates that the current core is still considered stronger than the rest of the conference pecking order, even as other franchises look to catch up.

For what to watch next, this kind of offseason ranking naturally turns into a checklist. As free agency continues and additional pieces get added, teams described as “gainers” should show whether their offseason improvement translates into clearer roles and better on-court rhythm. Teams grouped in the “second circle” should also be judged against the simplest test: can they elevate their performance against playoff-level opponents often enough to justify the optimism that July projections offer.
