Dissect the matchup

nflverse play-by-play + FTN charting · 2025 season (last season until three games are in)

Biggest mismatches

  • DEN defense (#1 sack rate generated) against a BUF offense ranked #19
  • BUF defense (#7 pass success rate allowed) against a DEN offense ranked #24
  • BUF defense (#6 completion % over expected allowed) against a DEN offense ranked #23
  • DEN sack rate (#2) against a BUF defense ranked #19 at stopping it
  • DEN rush success rate (#10) against a BUF defense ranked #24 at stopping it

A mismatch is a rank gap of at least a fifth of the league between an offense and the defense it faces on the same measure. Descriptive rows (pass rate, pace, direction) are shown for reading the game, not ranked. ▲▼ mark where the last three games sit clearly above or below the season number, in the direction that helps that side.
