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.
A high-end running-back decision where current workload and reception scoring matter more than reputation.
Christian McCaffrey: recent role lowers the estimate, and the matchup helps. Kenneth Walker: recent role raises the estimate, and the matchup helps.
Availability adjustments apply only when the source contains a Week 3 report. Older designations remain visible in the injury archive but do not reduce this projection.
