Floor and ceiling show the lower and upper ends of the player's recent scoring range. The projection is the middle estimate after current role, matchup, and same-week availability are applied.
Why the model leans this way
Role first. Matchup second. Availability always visible.
Two viable FLEX options with similar weekly projections, compared through recent opportunity, scoring format, matchup and current availability.
Christian McCaffrey: recent role is near baseline, and the matchup is tougher. Puka Nacua: recent role is near baseline, and the matchup is tougher.
Availability adjustments apply only when the source contains a Week 5 report. Older designations remain visible in the injury archive but do not reduce this projection.
Week 4 final result
Puka Nacua scored more. The pregame lean was wrong.
Christian McCaffrey: 14.5 Half PPR · Puka Nacua: 23.2 Half PPR.
