As a reminder, Total QBR is a quarterback rating that takes into account all of a QB’s significant contributions (passing, rushing, sacks, fumbles, penalties) to his team’s scoring and winning and summarizes them into one number on a 0-100 scale, where 50 is average.
Brady Quinn's 97.6 Total QBR in Sunday’s win over the Carolina Panthers was the highest by a Kansas City Chiefs quarterback in a single game in the past five seasons. He was 8-of-9 on 3rd down and 6-of-7 for 132 yards on passes traveling at least 15 yards beyond the line-of-scrimmage.
Matt Cassel has yet to have a game with six completions of 15 yards-or-more downfield this season.
One of the biggest plays for Quinn was his touchdown pass to Tony Moeaki on 4th-and-1 with two seconds remaining in the first half. According to ESPN’s win probability model, that completion increased the Chiefs’ chances of winning from 46.2 percent before the play to 64.4 percent following the score.
Quinn’s 97.6 Total QBR was also his career high as a starter; he never previously had a single-game QBR above 80 as a starter and hadn't had a start above 60 since Week 15 of 2009.
• Tony Romo had a season-high 96.7 Total QBR in Sunday night’s win over the Eagles. It was his first game with a QBR over 90 since Week 15 of 2011 against the Buccaneers. Since that game 22 different quarterbacks have posted a QBR of 90 or better, including Matt Flynn, Mark Sanchez, and the aforementioned Quinn.
• Colin Kaepernick had an 82.4 Total QBR in Sunday's loss to the Rams, his third straight start with a QBR over 70. Alex Smith has not had a single-season three-start stretch with QBRs above 70 in the past five seasons.
• Peyton Manning posted a 90.2 Total QBR in Sunday's win over the Buccaneers. Manning has six games this season with a QBR of at least 90, the most in the NFL. With his performance, Manning (81.1) also jumped Tom Brady (79.6) for the league lead in overall QBR this season.
TOTAL QBR AND WINNING
Total QBR can be used to quantify just how important the quarterback position has become to winning in the NFL. Looking back to previous years, the team with the higher Total QBR has won 86% of regular season games since 2008 (as far back as Total QBR goes). That is higher than the comparable mark for teams with the advantage in total yardage, turnover differential, and NFL passer rating.
