Weekly matchup rankings translate defenses into fantasy-friendly math using schedule-adjusted points allowed (Adj. FPA) to grade every defense for QBs, RBs, WRs and TEs. For the first three weeks, the rankings are opinion-driven with 2024 data as a snapshot. Standouts for Week 3 include Caleb Williams vs Dallas, Javonte Williams vs Bears, DK Metcalf vs Patriots, and Justin Fields vs Buccaneers, while noting that matchups are only one factor in start-sit decisions.
