NBA draft projections combine film, performance, role, physical measurements and judgments about how a player’s skills may translate to the league. A prospect can move up or down when new evidence changes that assessment. A mock draft is different: it predicts where teams might select players, not simply which players an analyst rates most highly.
How are NBA draft projections made?
There is no single public formula that represents every NBA team’s process. Public rankings and statistical models use different inputs and assumptions, while scouting boards may place more weight on film, role and projected skill translation. The available sources describe evidence streams evaluators can combine; they do not establish a universal team formula.
Game performance, role and translation
Evaluators watch game film and consider production, competition, the player’s role and specific skills: for example, shooting, creation, defense and decision-making. They then judge how those abilities might hold up in NBA competition and alongside different teammates and play types. NBA.com describes combine measurements as a snapshot and emphasizes considering them alongside real-game competition and play-type data: NBA.com’s 2026 combine data coverage.
One example of the game data available is Synergy play-type information from college seasons. It tracks how often and how efficiently a player performs actions such as isolations, post-ups, spot-ups, cuts and pick-and-roll as the ball handler or roll man. Those observations can add context to what a player’s film shows; they are not a common numerical grade that settles a prospect’s ranking.

Physical measurements and combine tests
The combine adds structured measurements and observations. In its 2026 overview, NBA.com lists height without shoes, weight, body-fat percentage, standing reach, wingspan, hand length and hand width. Tests include no-step and maximum vertical jumps, lane and shuttle drills, and a three-quarter-court sprint. Required shooting drills include off-the-dribble and spot-up shooting, a star drill, a side-mid-side drill and free throws. The overview also describes scrimmages and opportunities to meet team officials: NBA.com’s 2026 combine measurements and drills overview.
These results add evidence about a player’s size, reach, movement or shooting in a structured setting. They need interpretation: a drill or measurement does not by itself show how consistently a player will perform a skill in game situations. NBA.com’s 2026 AWS NBA Draft Combine Data Hub says it draws on 25 years of combine data for historical comparison; that figure describes the hub’s data history, not the predictive accuracy of combine results: NBA.com’s 2026 Data Hub description.
What can move a prospect’s ranking?
A ranking can change when an evaluator sees new information about a player’s skills, role, physical profile or likely NBA translation. It can also change if the evaluator revises how much weight to give evidence already available. The point is not that every new result should cause a move, but that new observations can alter the overall judgment.
- Measurements: Combine results may clarify a prospect’s height, reach or hand measurements.
- Movement and shooting tests: Drills can add observations about speed, agility, jumping or shooting in a controlled setting.
- Scrimmages and scouting: New live looks can reveal how a player performs against other NBA-caliber prospects or in a different role.
- Game context: Evaluators can reassess how a skill or play-type profile shown during the season may transfer to a different competition level or role.
These forms of evidence should be considered alongside game performance, not treated as conclusive on their own. In a 2024 example, NBA.com republished Jonathan Wasserman’s account that combine performances affected several prospects’ draft stock. Wasserman also described changing his mock projections after scouting in Chicago and speaking with scouts and executives. The same article said there was no consensus answer for the top prospect, illustrating that an updated projection is a changed judgment—not proof that an earlier observation was false: NBA.com’s 2024 account of Jonathan Wasserman’s mock draft.

Player evaluation versus predicted pick position
A prospect’s position in an analyst’s ranking can differ from the pick a mock draft predicts. A ranking orders players by the evaluator’s assessment of their quality or potential; a mock draft estimates what teams may do. Team context, preferences and new information about likely selections can affect a predicted pick order without changing the analyst’s view of which player is better. The sources do not establish confidential team boards, medical evaluations or the reasons behind any particular team decision, so those should not be assumed to explain an individual player’s movement.
Rankings, statistical models and mock drafts are not interchangeable
| Format | Question it answers | What it represents |
|---|---|---|
| Prospect ranking | How would this evaluator order the players? | An assessment of players, informed by the evaluator’s chosen evidence and assumptions. |
| Statistical model | What output follows from the model’s selected inputs? | A formalized estimate based on measurable factors and assumptions; public models need not match scouting boards. |
| Mock draft | Where might teams select players? | A forecast of team selections, which can diverge from an analyst’s player-quality ranking. |
| Consensus mock | What pick order emerges by combining forecasts? | A summary of multiple mock drafts, not an official NBA or team board and not proof of accuracy. |
A 2023 research paper studies mock-draft aggregation and proposes a method for combining ranked lists. That is a way to summarize forecasts, not evidence that a consensus mock is accurate or official: the 2023 paper on combining mock-draft rankings.

When a prospect moves up or down, first identify what changed: the player evaluation, the predicted selection order, or both. Then compare like with like and note when the evidence was gathered. A season-long game sample is not directly equivalent to a combine drill or a single scrimmage, and a collection of mock drafts is not the same thing as a player ranking.
- Observed production and role: What did the player do, in which competition and role, and how often did relevant actions occur?
- Skill translation: Which skills—such as shooting, creation, defense or decision-making—does the evaluator expect to transfer, and why?
- Age and physical profile: What was the player’s age at the time of the evaluation, and which measurements or athletic tests are being cited? Include the combine year and measurement context.
- Evidence and uncertainty: Is the claim based on a full-game sample, drills, scrimmages, or multiple forecasts? Is it a player ranking or a predicted team selection?
The cited sources identify relevant evidence categories but do not provide a shared numerical scale for comparing prospects across all of these dimensions. Combining unlike measures into a made-up score would give a false impression of precision. The 2024 example is useful for understanding how new scouting can change one analyst’s mock; it is not current advice about a future draft class.
