4.0 impact creditsHow the explosive profile and league overlay work
The NFL Explosive Index compares a player only with the same position. Its season model blends impact per opportunity, impact per game, positional share, long-touchdown rate, and longest gain; the career index blends 50% peak season, 30% recent three-season form, and 20% career share percentile. The league overlay reads synchronized Sleeper scoring for long-play and yardage-threshold bonuses. Those rules affect league-scored projections and fantasy value without rewriting the player’s league-neutral NFL explosiveness. Source: nflverse play-by-play and Sleeper league settings.
Availability + repeatability
Dependability Index
Two lenses, because weekly trust and dynasty durability are different questions.
100% scoring-floor hit rate • 100% workload stability
6% three-year game availability • 1 seasons of evidence
How dependability is calculated
Weekly dependability blends recorded-game availability, how often the player clears 60% of his median fantasy output, and stability of attempts, carries, and targets. Dynasty dependability emphasizes three-year game availability and repeat seasons, with a small age-context adjustment. Scores use PPR scoring and do not treat ceiling as reliability.
2021 Production & Efficiency
NFL production supplied by nflverse. Same-position ranks include qualified players from the selected season. Volume ranks require 50 pass attempts; rate ranks require 100. Fantasy output elsewhere on this page is recalculated with standard PPR scoring.
