Current availability is supplied by Sleeper’s player directory and is not a complete medical history. Sleeper’s documented player feed supplies status and practice context, not article headlines. No active designation does not mean the player has no prior injuries.

Big-play ability + league scoring
Explosive Play Profile
This player’s play-by-play analysis has not been built yet. The section remains visible so missing evidence is never mistaken for a zero score.
An administrator can start the complete recent-history build once in FantasyLeagueIQ → Player Data. It then populates every offensive player profile; league members do not need to sync players individually.
How 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.

Alexander Mattison Performance Trends
Last 8 recorded games, viewed through PPR scoring.
What these charts show
Fantasy points use the selected league’s scoring rules. Opportunity is attempts plus carries for quarterbacks and carries plus targets for running backs, receivers, and tight ends. Efficiency is completion percentage for quarterbacks and scrimmage yards per touch for other offensive positions.
Availability + repeatability
Dependability Index
Two lenses, because weekly trust and dynasty durability are different questions.
63% scoring-floor hit rate • 6% workload stability
92% three-year game availability • 3 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 20 touches; yards per touch requires 50. Fantasy output elsewhere on this page is recalculated with standard PPR scoring.
Recent production fallback. Athletic and draft inputs are supporting evidence—not a replacement for current projections, ECR, production, availability, or the selected league’s rules.
