Jessica Gridiron
Founder & Lead Analyst · Gridiron & Wine
Jessica Gridiron is the founder and lead analyst at Gridiron & Wine, a quantitative sports betting service that publishes verified daily picks across NHL, NBA, MLB, NFL, and college basketball. Every pick is logged, every result is published, and every model uses walk-forward temporal cross-validation so backtests cannot quietly peek at the future. The work focuses on the small, structural inefficiencies that betting markets miss — pace-adjusted efficiency in NBA, goalie workload effects in NHL, F5 starter-vs-bullpen separation in MLB, home-dog mispricing in spread markets — and converting those edges into transparently sized, tier-priced plays.
Credentials
- 3+ years building production sports betting models with live, publicly tracked output across NHL, NBA, MLB, NFL, and CBB.
- Walk-forward temporal cross-validation on every model — backtests are constructed so the model cannot see future data during training, which is the gold standard for honest pre-deployment evaluation.
- Verified +19.8% ROI across 633+ tracked plays. Every play is timestamped, every result published, every push and loss included.
- Fractional Kelly sizing baked into the tier system. Plays come pre-sized at 1u / 2u / 3u depending on model confidence and edge strength.
- Public CLV tracking — closing line value is logged on every play so the audience can verify the model is beating the close, not just winning by variance.
- Methodology and architecture for each model is documented in the public FAQ; nothing is gated behind “trust me.”

Background
Jessica built the first version of the Gridiron & Wine NHL model after years of frustration with the public pick-selling space — services that posted vague leans, quietly deleted losing weeks, and rebranded positive variance as “expertise.” The bar at Gridiron & Wine is the opposite: every play is logged with the price taken, every result is graded, and every model is published with its underlying methodology.
The service has expanded from a single NHL model to a portfolio of purpose-built quantitative models covering all five major North American betting sports, with verified track records for each. The shared discipline across every model: walk-forward temporal cross-validation, kill criteria for signal degradation, fractional Kelly sizing, and complete public transparency on wins, losses, and pushes.

Editorial Standards
Articles published under this byline follow strict editorial standards: every betting claim is sourced to a verifiable model output or public dataset, every backtest cited uses walk-forward temporal cross-validation, and every methodology described is the actual methodology in production — not a sanitized version. Where claims involve specific track records, those records are independently verifiable on the results page.
