GRIDIRON uses real prices and, for player props, checks recent NFL game logs when available. Last-5 averages and hit rates describe past results, not predicted win probabilities.

What GRIDIRON checks

Last 5 / 10 averagesOver / Under hit rateWeek-by-week history

Season-to-date regular-season results are compared with the exact sportsbook line. Games with no recorded result are excluded; pushes are not counted as wins. A 4/5 historical hit rate does not mean an 80% chance next game.

Only future games, one sportsbook and recent quotes are considered. Historical stats come from ESPN game logs when available; an unsupported player or missing data is labeled, not guessed. Confirm game-day inactive lists and sportsbook parlay prices. Limited Odds API plans may not include player props.

About GRIDIRON

Shared NFL research and automatic parlay suggestions for you and your friends

Automatic live odds

Nobody using GRIDIRON needs an API key. The owner configures the secret once in Cloudflare. All visitors share the live odds feed. Results are cached for a few minutes to reduce costs and may not reflect instantaneous line changes.

If the Odds screen says the shared feed is not configured, only the site owner can fix it through Cloudflare Settings → Variables and Secrets.

Install on iPhone

1. Open the website in Safari.

2. Tap Share → Add to Home Screen.

3. Tap Add and launch GRIDIRON from your Home Screen.

Data accuracy

Sportsbooks can change prices at any time. Parlay suggestions rank available market prices, not a validated prediction engine; GRIDIRON does not place wagers. Inactives and injuries need independent verification before betting. Multiple visitors share a limited API budget.
