No. No tool can tell you exactly who will get hurt and when. The frailty score is a durability index — it ranks each player's injury risk against the rest of the league based on workload, contact exposure, and durability history; it is not a percent chance of injury. Players flagged in the elevated-risk bands missed time at ~1.7× the league base rate in 2025 — meaningful edge, not a guarantee. INJSUR is a decision-support tool for entertainment and analysis.

An injury-risk scoring platform for NFL fantasy and sports betting. It uses machine learning informed by 25 seasons of historical data — with each score factoring the player's notable-injury history from the last five seasons (2022–2026) — to produce a calibrated frailty score for every rostered player.

The model was calibrated on 2024 injury labels and evaluated out-of-sample against the unseen 2025 injury set — 72% ROC-AUC, 32% top-20% capture rate, 78% of injured players ranked in the top half pre-season. Same model now scoring every 2026 roster live.

All 32 NFL teams, all skill-position players. Each position has its own calibrated scoring curve — a frailty of 60 on a RB is not the same as a 60 on a QB.

Yes. Scores recalculate with the latest stats every week throughout the season.

$39 for the 2026 season, or $99 once for lifetime access — same features on both. One-time payment, no auto-renew.

Roster construction differs mostly because DraftKings rewards volume more and FanDuel rewards touchdowns and roster flexibility more. That means DK lineups usually lean harder into high-target receivers, pass-catching backs, and stacking, while FD lineups are often more TD-centric and can tolerate more low-catch, high-touch players.

Main scoring differences

• DraftKings gives full PPR, so receptions matter more and high-volume pass catchers gain value.
• FanDuel uses half-PPR, so receptions are worth less and touchdown production matters relatively more.
• DraftKings also has yardage bonuses, while FanDuel does not, which further boosts players who pile up raw yardage.

Roster-building impact

• On DraftKings, you can lean into cheaper high-floor receivers and RB/WR stacks because catch volume adds up faster.
• On FanDuel, you generally prioritize touchdown equity, so bruising backs and red-zone threats become more attractive.
• FanDuel pricing is often softer, which can make lineups chalkier and reduce the need for extreme value hunting compared with DK.

Practical lineup style

• DK tends to reward balanced or correlation-heavy builds, especially when a player can score through receptions and yardage in addition to touchdowns.
• FD often pushes you toward a more star-driven build, since the scoring system makes elite TD outcomes more important than reception volume.
• A simple example: a 7-catch, 65-yard, 0-TD receiver is much more useful on DK than FD, while a 90-yard, 2-TD runner gets a bigger relative boost on FD.

If you want a quick shortcut: DK = volume and correlation; FD = touchdowns and raw upside.
