Reuse our numbers

Our original analytics are free to reuse, including in commercial work, under the Creative Commons Attribution 4.0 International license (CC BY 4.0). The one condition: credit Pigskin Nightly and link to the page the numbers came from.

What is covered

• The Lab: all twelve tools under /lab (Deserved Standings, Sliding Doors, Clock IQ, Ref Crew Report, Market vs Snaps, Scheme DNA, Game DNA, Paid vs Played, Loudest Stadiums, Turf vs Grass, Weather Ledger, Line Movement) and the validation page How sure are we.
• The Verdict: every page under /verdict and each club's verdict page.
• Each team's Scheme DNA page.
• The charts on those pages, their CSV and JSON downloads and the Lab API at /api/lab.

That means our own metrics and calculations: deserved wins and luck, win probability swings, fourth-down grades, Clock IQ, crew and venue effects, scheme fingerprints, value scores, the injury, weather and line-movement studies, and everything derived from them.

What is not covered

• Underlying data from other sources keeps its own terms: scores, schedules, rosters, injury reports, box scores and odds come from ESPN and sportsbooks; play-by-play and contracts from the open nflverse project. Facts such as a final score are not owned by anyone, but we cannot license other people's databases to you.
• Articles written by our club desks, the site's design, logos and team marks, player photos and embedded video.
• Bulk copying of the site. Scraping or mirroring pages is still not allowed under our terms of use. Use the JSON and CSV links instead: they exist for this.

How to credit us

Name the source and link to the page you used. Any of these works:

• Source: Pigskin Nightly, pigskinnightly.com/lab/deserved-standings
• Data: Pigskin Nightly (CC BY 4.0), with a link on "Pigskin Nightly"
• In a chart: "Chart data: Pigskin Nightly" under the chart, with the address

Every Lab and Verdict page has a Copy citation button with the exact line ready to paste. If you change our numbers or combine them with your own, say so ("adapted from Pigskin Nightly"). Do not suggest that we endorse your work.

Accuracy

The numbers update after every game and are estimates from models, not official statistics. How reliable each metric is, including the ones that are still mostly noise, is published on How sure are we. The license comes without warranties, as the CC BY 4.0 text explains.

Questions

For larger projects, custom cuts of the data or anything this page does not answer, write to [email protected]. We like hearing where the numbers end up.
