Quarters coverage on Seahawks' pass D

By Mike Sando


The Chicago Bears rank eighth in fourth-quarter passer rating (103.1) and Total QBR (73.8) at home this season.

Quarterback Jay Cutler and the Bears have to like their fourth-quarter chances against the Seattle Seahawks in Week 13.

Seattle's defense, though No. 1 in fourth-quarter passer rating allowed at home this season, ranks 28th in passer rating and Total QBR allowed during fourth quarters on the road.

All of this might make greater sense if Seattle's pass defense struggled on the road regardless of the quarter. However, the Seahawks rank fourth in passer rating (71.1) and eighth in QBR (41.2) allowed during the first three quarters of road games.

The first chart breaks down the home-road disparity for the Seahawks' pass defense in fourth quarters only.

Seattle's defense gave up decisive fourth-quarter touchdown passes in road games against Arizona and Detroit. Last week, the Miami Dolphins tied the game with a fourth-quarter touchdown pass before driving to the winning field goal.

The Seahawks' pass defense could have a new look in Week 13.

Walter Thurmond, activated from the physically unable to perform list in recent weeks, is expected to replace the injured Marcus Trufant in the nickel corner role. The team listed Trufant as doubtful with a hamstring injury. Thurmond was a starter last season before suffering a season-ending leg injury.

Miami's Davone Bess and St. Louis' Danny Amendola combined to catch five fourth-quarter passes for 113 yards working from the slot against Seattle.

The chart below shows fourth-quarter passing stats against Seattle based on where in the offensive formation opponents lined up. The stats are only for games when the Seahawks were on the road. I've included only those featuring at least three opponent first downs.
