Largest Total QBR Improvement
1st Half to 2nd Half, This Season

The Dallas Cowboys trailed the Cleveland Browns 13-0 at halftime on Sunday thanks to a first half in which Tony Romo was held to a 19.5 Total QBR. Romo bounced back to post a 78.0 Total QBR in the second half and OT en route to a 23-20 Dallas win.

Sunday was another example of Romo playing his best late: Romo ranks sixth in the NFL with a 72.0 Total QBR after halftime. Only Jay Cutler has seen his QBR improve more from the first half to the second half this season.

Sanchez bounces back, leads Jets

Mark Sanchez had a Total QBR of 84.0 in the New York Jets' win over the St. Louis Rams on Sunday. The Jets are now 23-3 in regular season games in which Sanchez had a QBR of at least 50 in his career and 8-23 when he has a QBR below 50.

Week 11 was a dramatic improvement for Sanchez who saw his QBR spike by 77.8 points compared to Week 10 (6.2). It was the largest in-season improvement from one game to the next for Sanchez since Weeks 4-5 of his rookie season in 2009 (0.7 to 85.7).

Quick hitters

Tom Brady took over the 2012 QBR season lead (81.6) thanks to the 93.9 Total QBR posted against the Indianapolis Colts on Sunday. Peyton Manning had held the lead at the end of each week since Week 6. This will mark the 1st time Brady has held the Total QBR lead since Week 2 of last season.

Drew Brees posted a season-high Total QBR of 95.6 in Sunday’s win over the Oakland Raiders. It was the 15th game in which Brees had a QBR of 90 or better since 2009, tied with Philip Rivers for the 2nd most in the NFL over that span (Aaron Rodgers – 16).

Total QBR and winning

Total QBR can be used to quantify how important the quarterback has become to winning in the NFL. Looking back to previous years, the team with the higher Total QBR has won 86 percent 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.

Keep in mind that just because a team wins a game with a lower QBR than its opponent does NOT mean that Total QBR was “wrong” or not as good for that game. That just means that the winning team was able to overcome its QB being outperformed by the opposing QB (on a rate basis), usually by playing better in other aspects of the game (rushing game, special teams, etc.).
