Changelog — GameDay Analytics

changed

Game Model admin navigation NFL

The NFL admin sidebar now includes a Game Model section linking to all eight game-line model admin pages.

added

Game Model external ranking comparison NFL

The admin power rankings can now be compared against outside sources — ESPN FPI refreshes automatically each week, and editorial rankings can be pasted in — with disagreements of five or more spots highlighted.

changed

Game Model pages reorganized NFL

Power rankings and the methodology write-up moved off the public site into the admin dashboard; the public game-model pages are now Picks, History, and Performance.

added

Game Model odds backfill report (Phase 8) NFL

A new report maps historical odds coverage gap by gap and prices what filling them would cost, so historical line data can be backfilled deliberately instead of blindly.

added

Game Model refinement loop (Phase 7) NFL

The game model now audits itself weekly: a refinement report analyzes residuals, injury-designation accuracy, and parameter sensitivity, and proposes tuning changes that can be applied as versioned, fully-audited parameter patches.

added

Game Model admin controls (Phase 6) NFL

Every number the game model uses is now editable from the admin panel with full change history and rollback — positional values, injury probabilities, situational adjustments, home-field advantage, stadiums, and per-player manual overrides — plus one-click recompute and report downloads.

added

Game Model public launch (Phase 5) NFL

Five new public pages on the NFL site: weekly game picks (spread, total, moneyline with edge tiers and units), power rankings with expandable player values, full pick history with CSV export, a performance dashboard, and the model methodology.

added

Game Model backtest and grading (Phase 4) NFL

The NFL game model has been backtested walk-forward across five seasons with honest, calibrated bet pricing, and every published pick now gets graded automatically against the final score and the closing line.

added

Game Model line engine (Phase 3) NFL

The NFL game model now prices every game: model spread, total and moneyline from team ratings, home field, rest/travel/situational spots, weather, and player-level injury impacts — all against a key-number-aware margin distribution built from a decade of results.

added

Game Model power ratings (Phase 2) NFL

Every NFL team now carries a decomposed power rating — efficiency, roster (every player on the depth chart has a visible point value), and market-implied — computed weekly back to 2021.

added

Game Model foundation (Phase 1) NFL

Laid the groundwork for the upcoming NFL game-line model: every model parameter (blend weights, injury pricing, situational adjustments, home-field advantage, stadium data) now lives in a versioned, admin-editable store with a full change history.

fixed

PFF Upload drop zone alignment NFL

Fixed the drag-and-drop area on the PFF Upload admin page overlapping the season/week controls.

added

WR Prop Model NFL

New machine-learning model projecting weekly receiving yards and receptions lines for every team's top wide receivers, with probability-priced edges against sportsbook props, agreement flags vs the sharp market, automatic post-game grading, and closing-line-value tracking. Live at /wr-model on the NFL site.

added

Expanded NFL data pipeline NFL

Nightly ingest now covers the full play-by-play feed, snap counts, injury reports, depth charts, Next Gen Stats receiving metrics, and a league-wide player ID crosswalk (2021-present, fully backfilled).

added

NFL player prop odds capture NFL

Hourly sportsbook prop snapshots (receiving yards, receptions, receiving TDs) with closing-line marking and a three-season historical closing-line backfill powering model calibration and CLV grading.

added

Player Analysis: instant player search NFL

Type a few letters in the new Player Search box to find any QB, RB, WR, or TE by name — no need to pick a position first. Selecting a player loads their analysis and sets the position automatically.

changed

Player Analysis now covers RB, WR, and TE NFL

The QB vs Team Defense page grew into Player Analysis: pick any QB, RB, WR, or TE and analyze them against a chosen defense with position-tailored stats, over/under hit rates, a threshold ladder, and the full game log. QBs keep their play-by-play target distribution. Old /qb-analysis links redirect to the new page.

added

QB vs Team Defense Analysis NFL

Analyze any QB against a chosen defense (or the whole league): over/under hit rates at your threshold, per-receiver target distribution built from play-by-play data, a threshold ladder, and every historical matchup. Find it under Analysis → QB Analysis.

changed

Prop Finder leaderboard and slate filters NFL

Added an All Props leaderboard that ranks every prop at a standard line by hit rate (including an ALL-positions board), a game-date selector that binds results to that day's slate with matchups and kickoff times (CT), and a Not Started filter that hides games already underway.

added

Prop Finder NFL

New Analysis section with a Prop Finder for NFL props: choose a season (2021-2025), position (QB/RB/WR/TE/K), prop, line, and direction to see every player's Season / L3 / L5 hit rates against that line, with game-by-game logs, a playoffs toggle, home/away splits, and usage filters.

added

Team statistics viewer NFL

New Team Stats page under Stats & Data: offensive, defensive, and combined league tables for any season (2021-2025) or single week, with sortable columns, live ranking, and top-8/bottom-8 color grading. Powered by nflverse weekly team stat lines plus final scores.

added

Player stats browser and player profiles NFL

New Stats & Data section on the NFL site: browse season-by-season player stats with search, position, team, and minimum-games filters — columns adapt to the selected position. Click any player for a full profile with season summaries, sortable game logs, and career totals covering 2021-2025.

added

nfl.gamedayanalytics.net launched with five seasons of historical NFL data (2021-2025) — every game, weekly roster, and player stat line from nflverse — plus the complete 2026 schedule, syncing nightly. Prop research tools and models arrive ahead of the 2026 season.
