What is not here, and why. The NFL stats page carries roughly sixty tracking-derived metrics — completion percentage over expected, air yards, separation, cushion, broken tackles. College play-by-play does not expose any of them. Rather than approximate them from box scores and call them the same thing, they are simply absent.
Receiving target counts are incomplete upstream for many schools, so raw targets are not ranked. Share metrics are team-relative and stay internally consistent.
Garbage-time exposure is a warning metric — it is ranked low-to-high, because a small number means the production came in competitive football.
