Snap & Target Volume
Snap share, target share, and weighted opportunity (WOPR) — the volume that underpins every yardage and reception prop.
Source: nflverse (snap counts, weekly player stats + play-by-play). WOPR = 1.5×target share + 0.7×air-yards share. EPA/Play & Succ% are play-weighted over the player's targets, carries & dropbacks. RACR = receiving yards ÷ air yards. L4 = snap-share trend vs season.
