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 relevant running-back options in a similar weekly range, compared through touches, receiving work, matchup and current availability.
Christian McCaffrey: recent role is near baseline, and the matchup is tougher. Jahmyr Gibbs: recent role is near baseline, and the matchup helps.
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
Jahmyr Gibbs scored more. The pregame lean was right.
Christian McCaffrey: 14.5 Half PPR · Jahmyr Gibbs: 15.7 Half PPR.
