Our weekly deep dive into NFL quarterback play. Many thanks to our friends at ESPN Stats & Information for supplying analysis and data to drive this post. Remember that Total QBR runs on a scale of 0-100. The scale for traditional passer rating is 0-158.3.
Passer rating: 131.7
Analysis: How sharp was Foles on Sunday night? He completed 21 of 25 attempts, and of those four incompletions, three were thrown away and one was dropped. That makes Foles the first quarterback since the start of 2008 to attempt at least 20 passes and not have at least one pass judged to have been thrown off target for an incompletion. Once again, Foles and the Philadelphia Eagles feasted on play-action (16 of 25 attempts). He completed all six of his passes that traveled more than 10 yards downfield, including five that went at least 15 yards and three of at least 21 yards.
Passer rating: 136.5
Analysis: Sunday brought arguably Dalton's sharpest game of the season, albeit against the Minnesota Vikings' hapless defense. The Vikings sent four or fewer pass-rushers on 27 of his 38 pass attempts, and Dalton picked them apart by completing 21 of those throws for 293 yards. He had a bit more trouble against the blitz, completing 6 of 11 passes, but three of those connections went for touchdowns. Overall, the Vikings put him under duress on only one of his 41 dropbacks. Sunday marked Dalton's third consecutive turnover-free game, and his two sacks came in the fourth quarter after his Cincinnati Bengals had established a 28-point lead.
Passer rating: 98.7
Analysis: On this Sunday, at least, Romo provided a clutch performance in the fourth quarter. He had more completions (nine) and yards (140) in the final period than he did in the first three quarters (eight, 86) combined. Both of his touchdown passes, including the winning throw to DeMarco Murray, came from outside the pocket. Overall, he completed 5 of 7 passes on third down; four converted a first down. He also converted both of his fourth-down attempts, among them the game winner. Looking ahead, of course, Romo is 1-6 in his career in Week 17 or playoff games when his team needs a victory in order to advance. The lone victory came in the 2009 wild-card round against the Eagles.
Passer rating: 53.9
Analysis: Stafford's fourth-quarter issues continued Sunday against the New York Giants. He threw his fifth fourth-quarter interception in the past six games, although Sunday's calamity came off a tipped pass. In the fourth quarter and overtime, Stafford completed 5 of 11 passes for 39 yards, including the interception, for a 5.5 QBR. He now has a 10.6 QBR in his past six games, during which the Detroit Lions have gone 1-5. That's the second-worst mark in the NFL over that span. In his first nine games, Stafford had compiled a 90.1 QBR in the fourth quarter. Overall, Stafford has set a career high with 23 turnovers.
Passer rating: 81.8
Analysis: Newton had a QBR of 3.0 Sunday against the New Orleans Saints before leading the winning drive. He completed 3 of 4 passes for 65 yards and a touchdown on that possession. Overall, however, Newton was bottled up by the Saints defense. He managed just 7 yards on three rushes, excluding kneel-downs. One of those was deemed a scramble via video analysis, gaining 2 yards, the lowest total of scramble yards in his career. He completed 1 of 5 passes and took three sacks on third downs, and somehow his Carolina Panthers became the first team in two years to win a game without converting a single third-down opportunity.
Passer rating: 45.6
Analysis: Tannehill absorbed seven sacks in a shutout loss and was put under duress on eight other dropbacks. The combined sack/duress total of 15, on 34 dropbacks, translated to the most pressured game by percentage (44) that Tannehill has played in this season. He completed only 2 of 8 passes in those situations for 15 yards. He and the Miami Dolphins tried to drive the ball downfield, but all 10 of his passes that traveled more than 10 yards downfield were incomplete. It had been four years since an NFL quarterback had thrown at least that many downfield passes without a single completion. As a result, Tannehill averaged 3.0 yards per attempt, the lowest total of his career by far. His receivers dropped 11.1 percent of his passes, the NFL's highest mark of Week 16.
