NBA 2026: Training Camps Open, Data Stays Shut

NBA 2026: Training Camps Open, Data Stays Shut

On September 29, 2026, JJ Redick stood in front of a microphone and said something I copied word for word into my notebook: "No one is a championship level team on September 29th." He said it at the Philadelphia 76ers opening press conference, after LeBron James's first practice alongside Joel Embiid. LeBron is 41 this year and entering his 24th season, a milestone with no precedent in league history.

That same week, Giannis Antetokounmpo wore a Miami Heat jersey, lined up next to Bam Adebayo and Klay Thompson. Kawhi Leonard returned to Toronto, the city where he lifted the trophy in 2026, after a turbulent ending in Los Angeles. Stephen Curry signed an extension with the Golden State Warriors. Six new head coaches took their seats at once. And in New York, Jalen Brunson, the reigning Finals MVP, entered the season as the champion who must defend.

A summer like that creates the feeling that everything is settled. I do not trust that feeling.

The source material and what we do not know

I need to be clear about the material in my hands. It is a season-opening preview written as a running narrative: listing transactions, recounting press conferences, quoting statements. The report carries no statistical table. No OffRtg, no DefRtg, no Pace, no eFG%, no salary data, no contract structure detail. For someone who works with team data, that is an uncomfortable starting point: leads without a thermometer.

That does not block analysis. It only forces every conclusion to carry a confidence label, and I will label them throughout this piece.

I once wrote a flatly confident prediction for a major outlet before a match in Doha in November 2026. I wrote "will win," "minimum three goals." I was wrong. I spent the following two weeks rewatching 47 matches from Gulf-region tournaments across ten years, in order to understand that temperature and altitude are real variables rather than marginal notes. I once thought I was right. Qatar taught me I was wrong. Since then, every analysis I write opens with a list: what we do not know.

The unknown list for the 2026 season has five entries. Where LeBron and Embiid divide ball control. Where the open space sits when Giannis and Bam share the floor. How many games Kawhi's knee can carry. How long six new coaches need to install their systems. And how much expectation Brunson can shoulder without changing how he plays.

Philadelphia: a two-hub problem

LeBron James has never operated at his peak next to a center who plays heavy at the rim. Chris Bosh spaced out. Kevin Love spaced out. Anthony Davis rolled and popped. All three belonged to the archetype of big men who can leave the area under the basket to clear a driving lane for him.

Joel Embiid is a different archetype. He is an offensive hub at the rim and in the mid-post, a player who needs the ball in favorable positions to use his full skill set. Placing two players who both need the ball in overlapping zones is a problem with no ready-made answer, and the report offers no hint about the system the staff intends to build.

The report quotes LeBron saying he wants to be "the final little piece" that gets Embiid over the hump. That is a handsome quote, but it is not yet a scheme.

The most plausible scenario sits in a high pick-and-roll between LeBron and Embiid. If the defense drops, LeBron has a driving lane and a kick-out, while Embiid has a pop for the midrange. If the defense switches, the one-on-one efficiency of both becomes the deciding variable. I have no metric in hand to test this hypothesis. Confidence: medium, based on archetype principles rather than on data from the report.

LeBron's two-year deal sends another signal: Philadelphia is operating inside a two-season window, not a long-term project. Every decision about roster depth should be read against that timeline.

Miami: a dream defense and a clogged corridor

Giannis Antetokounmpo moved to Miami at 31 to 32 years old, meaning he remains inside his physical peak. Pairing him with Bam Adebayo creates a fearsome defensive frontcourt: switchable at every position, covering multiple gaps, giving opponents no clear target to attack.

On the offensive half, the story is different. Two big men sharing the floor occupy two spots near the rim. Klay Thompson is likely the answer to the spacing problem, but the real question sits in the closing lineup: who stands outside, who stands inside, and who gets sacrificed when the game reaches the fourth quarter.

Miami's spacing question may be the single most important question in the entire Eastern Conference in October. The report provides no data to answer it. Confidence: medium.

Giannis leaving Milwaukee also says something about motivation: he placed competitive infrastructure ahead of loyalty to one team. If the Miami spacing experiment fails early, that becomes a variable worth tracking in every future negotiation. A transfer is not arithmetic, it is a negotiation between people and numbers.

Toronto: the return and one knee

Kawhi Leonard returned to the place where he was once king. Good story, and the market loves it. But his availability is the largest variable of all and cannot be forecast by any model.

Every tactical analysis of Toronto must carry a condition: if Kawhi is healthy. He belongs to the archetype whose presence restructures an opponent's defense, and simultaneously to the archetype around whom a coaching staff can no longer plan long term. The turbulent ending in Los Angeles is part of that picture, and the report mentions it only as an emotional detail. Confidence on this risk: medium to high.

Golden State: the shooter's exception

Stephen Curry signed an extension. For a guard who lives on shooting technique rather than explosive athleticism, the decline curve tends to be gentler than for players dependent on speed and verticality. This is the only part of the report that reads as stability rather than volatility. Confidence: medium.

New York: the defender of the throne

Jalen Brunson is the reigning Finals MVP, and the Knicks are the defending champions. That is an achievement fact, not a per-game statistical line. I have no numbers in hand to judge how he sustains that level now that every opponent has spent a summer studying him.

Six hot seats at once

Six new head coaches — Dusty May in Dallas, along with Mosley, Sweeney, Jenkins, Splitter and Nori — introduce a league-wide layer of uncertainty. Every new system needs installation time, and most teams that change coaches lose at least a quarter of a season shaping an identity. Add six cases at once to a summer that already reshuffled personnel through four major transactions, and you get a season in which the number of variables exceeds the number of data points.

Playoff transferability: not yet assessable

The report supplies no playoff-tested lineups, no adjustment strategies, no targeted-defense context. The single relevant data point is Redick's line on September 29. It implies that in-season team formation is an ongoing process, not a finished product.

The contrarian angle: changing teams is not changing fortunes

This report is built to sell certainty. Every summer is. The problem is that correlation gets read as causation: teams with big stars are treated as contenders, stars changing teams are treated as game changers. History does not support that reading.

Based on my experience tracking games across many seasons, there is one layer of information I always check before trusting a roundup: who selected these stories, and what did they want them to say. Six new coaches are good material for the opening section. Four stars changing teams is good material for headlines. But data on how they play together does not yet exist, and it will not exist until the season has run a few dozen games.

In 2026 in Doha, I had four years of qualifying data in hand and I was still wrong. Here I have a preview carrying not a single metric. The reasonable confidence level for any statement about the 2026 season should be set far lower than the tone of the report itself.

What to watch in the next round

There is one signal I will track over the first twenty games: Miami's closing lineup, and how Philadelphia divides ball control in the fourth quarter. Those two things will say more than any press conference. Numbers do not lie, but the person choosing them does. When the arena empties, only the data whispers the truth. Data is a mirror; do not get angry when it reflects an ugly truth.
