How RookieRadar works

Not financial advice

RookieRadar and The Rookie Report publish stats and market links for research. Nothing here is financial or purchasing advice. Card values can fall, so do your own research.

Football: data and methodology

• Source: Stats & snap counts: nflverse open data (snap counts sourced from Pro Football Reference via nflverse). This build: 2026 regular season, Weeks 1-6 (Week 7 is in progress and will be added once every game is final). Data fetched 2026-10-25T19:22:15+00:00 UTC.
• Who's tracked: Rounds 1–3 plus any later-round or undrafted rookie with 100+ snaps or a 25%+ snap-share game.
• Snap share: a player's offensive (or defensive) snaps ÷ his team's total for that game. Games a player missed while his team played count as 0%.
• Production: PPR fantasy points for offensive players. For defenders, RookieRadar defensive impact points = solo tackles + 0.5×assists + 1×TFL + 4×sacks + 1×QB hits + 5×INT + 1.5×passes defensed + 3×forced fumbles + 2×fumble recoveries + 6×defensive TDs. Offensive linemen are tracked by snaps only.
• Trend: latest game vs. the average of the previous (up to) three team games. Score = snap-share change in percentage points ÷ 10 + production change ÷ 5 (offense) or ÷ 4 (defense). ≥ +1.5 is "Up", ≤ −1.5 is "Down"; players who haven't topped 15% snap share are "Depth".
• Up and down lists: players listed as up must have played 20%+ of snaps in the latest game; players listed as down must have averaged 25%+ beforehand.
