Seahawks cornerback Marcus Trufant led the NFL in penalty yardage with 133.
Two other NFC West players -- Kurt Warner and Deuce Lutui of the Cardinals -- reduced penalties dramatically. Warner committed three, down from 11 last season (most were delays of game which might not have been his fault in every case). Lutui committed four, down from 12.
