QBR ranks: Tarvaris Jackson good enough
By Mike Sando
The Seattle Seahawks can live with -- and win with -- the passing Tarvaris Jackson has provided them over the last two games.
Jackson's improved health has helped him complete 70.1 percent of his passes with two touchdowns, no interceptions, an 8.6-yard average per attempt and a 110.9 NFL passer rating during victories over Philadelphia and St. Louis. Seattle converted 8 of 13 third-down passing opportunities.
Two fumbles, including one from a botched exchange on third down in Rams territory, dropped Jackson's Total QBR from 59.1 to 39.4 at that point in the game. And because Seattle did not extend its lead, Jackson's final-game QBR checked in at a modest 41.1 -- right around his cumulative season score. That was more than enough for Jackson and the Seahawks to beat the Rams, 30-13.
Sam Bradford struggled on an injured ankle and against Seattle's aggressive cornerbacks. He failed to complete any of his five goal-to-go passes, dropping his season total to one completion in 16 attempts on those throws. The interception he threw right after halftime contributed to a season-low 8.8 QBR, with 50 representing average play and 100 the maximum. Bradford appeared to have trouble stepping through some throws, causing some to fall short of their targets. The intercepted pass was slightly behind its target.
Note: Newly configured expanded QBR pages show breakdowns across multiple categories, including by division. Some of the individual leaderboards are filtered to include only quarterbacks with 30 action plays in a game.
Update: Yards after catch are another key factor in these calculations. Receivers get more credit than quarterbacks for yards gained after the reception. Seattle's Doug Baldwin gained 73 of his 93 yards after the catch, a single-game high for a Seattle player this season, according to ESPN Stats & Information. The Rams' Steven Jackson gained 50 yards on a screen pass, another play featuring significant YAC.
Quick thoughts on how NFC West passers graded out in Week 14 according to Total QBR, with NFL passer ratings in parenthesis as a reference point:
- John Skelton, Arizona Cardinals (44.1 QBR, 106.5 NFL rating): See previous item.
- Tarvaris Jackson, Seattle Seahawks (41.1 QBR, 96.4 NFL rating): Jackson completed 21 of 32 passes for 224 yards with one touchdown, no interceptions, two sacks and five rushes for four yards. He fumbled twice, losing one. Jackson recently edged into the NFC West lead for season-long QBR. He posted a season-high 76.9 against Philadelphia in Week 13. The Rams have allowed opponents a 52.1 QBR, 18th-best in the league. Seattle's next opponent, Chicago, ranks 15th at 49.2 allowed.
- Alex Smith, San Francisco 49ers (9.4 QBR, 62.3 NFL rating): See previous item.
- Sam Bradford, St. Louis Rams (8.8 QBR, 49.9 NFL rating): Bradford completed 12 of 29 passes for 193 yards with no touchdowns, one interception, three sacks and two rushes for minus-1 yard. He did not fumble. The Seahawks now rank 11th in QBR allowed (43.8). The Rams' next opponent, Cincinnati, ranks 12th (47.8).
The chart below shows how quarterbacks from games involving NFC West teams fared in Total QBR for Week 14.
The clutch-weight average column reflects game situations, not how well players performed during those situations. Any clutch average above 1.0 reflects a quarterback performing in higher-pressure situations.
