Youth and professional evidence does not establish NCAA recruiting effectiveness or applicability to other sports.","evidence":"Twenty studies were synthesized after a June 15, 2025 search of four databases. The authors used an adapted PROBAST-informed appraisal. Table 3 lists external validation as not reported. Heterogeneous tasks prevented quantitative synthesis; there is no common baseline or pooled effectiveness estimate.","architectureImplications":"Interpretation: Retain source provenance, feature timing and model versions; separate simulated attributes from observed athlete records. Compare a simple baseline with any proposed model using independent teams and later seasons.","governanceImplications":"Interpretation: Define the target decision before modeling; market-value prediction is not automatically a defensible recruiting objective. Preserve accountable scouting judgment and a correction route.","securityPrivacyImplications":"Interpretation: Authorize each data feed, limit recruiter access, document consent and retention, and prevent sensitive assessments leaking into unrelated decisions.","caveats":"English-language peer-reviewed evidence only; grey literature excluded. Predominantly male and European evidence, virtual datasets and selective cohorts constrain transfer. Review-level appraisal was inspected; underlying studies and supplement were not independently replicated.","streamIds":["college-athletics"],"roles":{"sales":"Interpretation: Recruiting directors, soccer coaches, analysts and compliance teams need to distinguish a useful shortlist aid from an unsupported talent score. Ask what decision is difficult, which prospective outcome defines success, whose data are missing and whether historical scout judgments already shape the labels. Offer a bounded audit of a proposed tool and its evaluation plan. The value hypothesis is more transparent comparison and a better understood error burden, not improved win rates or recruitment yield. This review cannot establish that a vendor outperforms local staff. Avoid transferring professional market-value claims to scholarships or assuming performance on male European datasets applies to a women's collegiate program.","engineering":"Interpretation: Before integration with recruiting systems, define athlete identity, feature timestamps, data rights and an untouched test cohort. Evaluate simple baselines, calibration and ranking stability using later seasons or separate institutions; detect duplicate athletes and information unavailable at decision time. Keep simulation-derived inputs out of real-athlete validation unless separately justified. Record missingness and subgroup error rather than presenting one headline score. Secure exports and analyst workspaces with least privilege. Proposed proof of value should test whether an assisted shortlist adds useful information beyond current scouting under equal review time. No infrastructure scale, generative copilot or autonomous recruiting agent is validated by this review.","delivery":"Interpretation: The recruiting director should own decisions and an analyst should own data quality and evaluation, with compliance and privacy reviewers approving use boundaries. Start in shadow mode, document corrections and overrides, and train scouts to interpret uncertainty. Dependencies include reliable follow-up outcomes, consistent labels and enough representative cases to assess transfer. Proposed acceptance requires documented data rights, a reproducible comparison with current practice, no unresolved leakage, and an explicit decision on subgroup limitations before operational use. These gates are proposed, not observed. Risks include entrenching historical selection bias, treating absent data as poor potential and expanding beyond the validated sport or population."},"retrievedAt":"2026-09-13T03:01:26Z","enrichedAt":"2026-09-13T03:03:40Z","enrichmentBasis":"retrieved source","accessibilityWorkforceImplications":"Interpretation: Train scouts in uncertainty and preserve intelligible explanations and human review. No workforce saving or disability-access outcome is established.","procurementImplications":"Interpretation: Require independent validation evidence, feature definitions, population coverage and access to error analysis; decline guarantees based solely on internal accuracy.","operatingModelImplications":"Interpretation: Separate model maintenance from selection authority and schedule re-evaluation when cohorts, data providers or recruitment goals change.","updateExplanation":"New URL after paginated review of all 247 archive resources and targeted talent-identification search.
