Methodology and data boundary

2025 REG is historical measured evidence. Average weekly grades are arithmetic means of finite team-game grades and are not official PFF season grades. 2026 PRE is a separate partial sample, and future preseason rows are excluded from performance. The passing attack map sums 2025 receiver targets into 12 PFF depth-and-direction zones from the offense perspective; it measures concentration, not efficiency. The 2026 schedule comes from the committed NFL schedule snapshot. Current roster, injuries, and projections are unavailable until a future provider snapshot is integrated. No ATS, moneyline, total, prop, side, or win prediction is inferred. Source: PFF, NFL Full Team Reports; National Football League 2026 schedule snapshot.
