The read

On rating alone Seattle Seahawks are 6.6 points better (#1 vs #13 of 32), and SEA add 0.0 for home field. The clearest mismatch is the passing game: SEA passing ranks #7, LAC defends it at #8; the other way LAC #24 into SEA's #6.

Biggest mismatches

  • SEA defense (#1 explosive rush rate allowed) against a LAC offense ranked #28
  • SEA defense (#1 rush success rate allowed) against a LAC offense ranked #25
  • SEA defense (#1 yards / rush allowed) against a LAC offense ranked #25
  • SEA defense (#6 red-zone touchdown rate allowed) against a LAC offense ranked #30
  • LAC defense (#1 interceptions forced) against a SEA offense ranked #25

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.
