Main reading
His signals support him (#33 of 39); comparables qualify it (#20 of 36).
Why he is here
The NCAA model places him #38 of 39: his individual signals back it (#33) and the comparables lens places him relatively higher on the board (#20 of 36) — a relative rank: his analogues reached the NBA 10 % of the time, the model gives him 14 %. Market: #58.
Measured over 36 games with a box score · 2025-26 · UCLA Bruins
- fact6 % probability of an NBA career (≥ 2,000 min). On the model's scale: context +2.23 · player −0.08. With average opponent and team, the same profile would give 0.7 %; on the environment alone, 6 %.
- factMeasured environment: UCLA Bruins, strength +6.0 (+0.9 sd) · average opponent +4.0 (+1.6 sd) — environment #35 of 39 ranked
- factHis individual signal adding the most: Blocks per 40 2.4 (+2.3 sd · contribution +0.87). On his individual signals alone he would be #33 of 39.
- factHistorical comparables: 3 of 30 similar university seasons reached the NBA (10 %) — #20 of 36 ranked in that lens. The model gives him 14 % to reach the NBA: the comparables are more conservative than the model for all 36 ranked, which is why this lens compares ranks, not figures.
interpretationHis individual signals back the rank and the comparables lens places him relatively higher among the ranked. It is a relative position within the board, not an arrival rate: his analogues reached the NBA 10 % of the time and the model gives him 14 %. The two lenses disagree, and that lowers the conviction.
Where the rank comes from: how much his individual signals contribute and how much his environment (model scale). Below, the probability with an average opponent and team, and the probability on the environment alone.
Potential
Categorical reading of the ceiling the accredited evidence supports. Not a score: it starts from the NCAA model (if any) or from the market prior and only moves one level with our own evidence, declared piece by piece.
factStarts from the NCAA model: 6% probability of an NBA career (#38 of 39 measured). → Limited
- ◎The market (#58) does not disagree with the model enough to move the reading.
- ◎On his individual signals alone he would be #33 of 39: consistent with his model #38.
Evidence moves the reading one level at most, in the direction the sum of the evidence pushes. · Confidence: NCAA season with ≥ 15 games with a box score and ≥ 60% of the team's games.

Strengths
Signals that add the most
What travels: holds up against strong opponents
—
An individual signal is transferable if it holds against opponents rated +8 or better (≥ 90% of its season value). What evaporates as the level rises is stated.
Risks and what would change our mind
Signals that subtract
- ▼Comparables: only 3 of 30 historical analogues reached the NBA
- ▼Junior: the model does not adjust for age or class; the same production from a freshman projects higher
Would make us move him down
- ▼Age: we do not adjust for it (Junior); the same production from a freshman projects higher
- ▼More sources consolidating the consensus #58
Would make us move him up
- ▲More scoring per 40 min: today 14.5 (−0.1 sd)
- ▲Combine measurements (wingspan, reach, athleticism): we do not have them today
- ▲A second source placing him nearby: today the consensus is a single mock
What to watch until the Draft
- →The 2026-27 season: every new box score is measured and can move the rank
- →The 2027 Combine (May): wingspan, reach and athleticism we do not have today
- →The mocks: captured daily; today the consensus is 1 source(s)
- →His minutes (20.2 per game): a drop would show in the box score before any news

Does our position hold? · The three lenses
- ◎On his individual signals alone he would be #33 of 39: the same zone as SW #38
- ◎On his environment alone (opponent and team) he would be #35 of 39, with 6 %
- ◎The comparables lens places him relatively higher on the board: #20 of 36 (−18 places versus SW #38). It is a relative rank, not a rate: 10 % of 30 similar seasons reached the NBA; the model gives him 14 % to reach it
Three independent lenses against our own place: his individual signals alone, his environment alone and the historical comparables. A lens disagrees when it lands 8 places away or more. SportiveWorld can be wrong: this is where it shows.
Conviction
- ✓Sample: 36 of 36 games with a box score (100%)
- ✓Standardised by the Scout census (own season profile)
- ✗The consensus is a SINGLE source (1): it is not a market
- ✓His individual signals alone leave him in the same zone (#33 versus SW #38)
- ✗Historical comparables place him far away (#20 of 36 versus SW #38)
Why this gap exists ▾
On our side the gap decomposes exactly: which dimensions push the rank up and which hold it back. On the consensus side we only see the rank: its sources publish rankings, not reasons, so why they place him there is UNKNOWN. All we can say is what our model does NOT measure.
factSportiveWorld #38 · consensus #58: 20 places higher. Pushing up: Opponent quality · Team strength · Box-score defence · Efficiency. Holding back: Minutes · Creation. Consensus sources: 1.

Pushes the rank up
Holds the rank back
What our model does NOT measure (it could explain part of the gap; the consensus does not publish its reasons)
- ◇Age and class (Junior): the model does not adjust for them and favours the productive veteran
- ◇Physique and athleticism: no Combine measurements; only the listed height
- ◇Projection, film and future role: not in the box score

Declared limits
- · No adjustment for age or class (the historical census lacks them): bias in favour of the productive veteran.
- · Physical measurements and the combine are not in the model: they are shown as context.
- · Calibrated on the NCAA only: ACB, EuroLeague and FIBA are not scored.
- · The mocks' history starts on 2026-09-13: before that date there is none (the ingester overwrote them daily).
