NBA draft projections are informed judgments, not the output of one public formula. Evaluators combine game film and production with a prospect’s skills, role, age, physical profile and likely fit at the next level. New evidence can change how those factors look—or how much weight an evaluator gives them. A prospect ranking orders players by an assessment of their ability; a mock draft predicts which players teams may select.
How NBA draft projections are built
Evaluators draw on several kinds of evidence rather than a single decisive metric. They study game film and production, consider the player’s role and level of competition, and judge whether skills are likely to translate to NBA play. Age and physical profile may also inform the assessment. Public statistical models can formalize some inputs, while scouting boards may put more emphasis on film and role; there is no single public formula that represents every NBA team’s process.

Game performance and role
What a player does in games—and the role in which they do it—helps put raw production in context. NBA.com’s 2026 combine coverage describes college-season Synergy play-type data that tracks how often and how efficiently players perform actions such as isolations, post-ups, spot-ups, cuts, and pick-and-roll as a ball handler or roll man. Those game-based observations can be considered alongside combine measurements and drills, rather than treated as interchangeable with them. NBA.com’s 2026 Combine Data Hub overview describes the combination.
Measurements, drills and scrimmages
At the 2026 NBA Draft Combine, NBA.com reported measurement stations for height without shoes, weight, body-fat percentage, standing reach, wingspan, hand length and hand width. Testing included no-step and maximum vertical jumps, lane and shuttle drills, and a three-quarter-court sprint. Required shooting drills included off-the-dribble and spot-up shooting, a star drill, a side-mid-side drill and free throws. The overview also described scrimmages and opportunities to meet team officials. These are evidence sources, not a standalone verdict on a player. NBA.com’s 2026 combine overview lists the stations and activities.
#1 Best Overall
NBA.com says combine measurements are a snapshot: evaluators also need to consider how a prospect’s abilities show up in real-game competition and alongside play-type data. Its 2026 AWS NBA Draft Combine Data Hub description says the experience draws on 25 years of combine data for historical comparison. That figure describes the data available in the Hub, not the predictive accuracy of combine measurements. NBA.com’s Data Hub description provides that context.
What can change a prospect’s ranking?
A ranking can move when new observations alter an evaluator’s view of a player’s skills, role, physical profile or likely NBA translation. It can also move when the evaluator revises the weight given to evidence already available.
- Measurements: Combine data can clarify a prospect’s measured size, reach or hand dimensions.
- Movement and shooting tests: Sprint, agility, jump and shooting-drill results add observations about athletic movement and shot-making in a structured setting.
- Scrimmages and scouting: Live play can show how a prospect competes against other NBA-caliber players or handles an unfamiliar role.
- Game evidence: New film or closer attention to role and play-type performance can change an evaluator’s view of what a skill means in context.
Drills and scrimmages should be checked against game performance. A striking combine result is one piece of evidence, not proof that a prospect’s overall evaluation should rise or fall.

In a 2024 account republished by NBA.com, Bleacher Report’s Jonathan Wasserman said combine performances affected several prospects’ draft stock. He also described changing his mock projections after a week of scouting in Chicago and conversations with scouts and executives. The same article noted there was no consensus answer for the top prospect. It illustrates that evaluations and forecasts can change as new observations arrive; it does not establish a universal ranking method or a rule about how much a combine performance should matter. Read the 2024 account on NBA.com.
Why a ranking and a mock draft can disagree
A prospect ranking answers, “How does this evaluator order the players?” A mock draft answers, “Where might teams select them?” A player can rank highly on an analyst’s board yet be projected later because the mock is forecasting team choices, not simply reproducing that board. Team context and new information about what teams may do can affect predicted pick order without changing an analyst’s view of player quality.
Consensus mocks combine forecasts from multiple sources to summarize a projected pick order. A 2023 research paper studies mock-draft aggregation and proposes a method for combining ranked lists. Aggregation does not turn a consensus mock into an official NBA or team board, nor does it establish that the combined forecast will be accurate. The 2023 paper on mock-draft aggregation describes the forecasting problem.

When a prospect moves, first check what moved: the evaluator’s ordering of players, a predicted draft position, or both. Then look for the evidence and its date. A useful comparison keeps the same dimensions in view:

- Skill translation: What evidence supports the view of the player’s shooting, creation, defense or decision-making at the NBA level?
- Age and physical profile: What was the player’s age at the relevant date, and which measurements or athletic tests are being cited, from which combine year?
- Evidence quality and uncertainty: Is the claim based on a season of game film, a drill or scrimmage, or several forecasts? Is it a player-quality ranking or a team-selection prediction?
These categories help explain why projections differ, but the cited sources do not establish a common numerical scale for combining them. Do not treat unrelated measurements, scouting judgments and mock positions as if they produced one comparable score. A change in a projection is evidence that an estimate changed—not proof that earlier observations were false.
What public projections cannot tell you
Public rankings and models are estimates built with different information and assumptions; they are not a complete view of every team’s decision process. The sources cited here do not document confidential team boards, medical evaluations or the full reasons behind a particular team decision. Without direct evidence for an individual move, those factors should not be presented as its known cause.
The combine details above are specific to NBA.com’s 2026 overview, while the ranking-movement example is from 2024. Combine participants, formats and draft evaluations change from year to year, so a dated example should not be read as current advice about a future draft class.
