Russell Wilson ran for three touchdowns and threw for another against the Bills to post the highest single-game QBR this season.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. Since the start of 2008, the team with the higher QBR has won 86 percent of the time.

Highest Single-Game Total QBR

This Season

Russell Wilson posted a 99.3 Total QBR in Sunday's win over the Buffalo Bills, the highest single-game QBR this season.

Wilson did much of his damage with his legs, rushing for career-highs in both yards (92) and touchdowns (3).

His QBR followed suit because he added 9.5 points above average (PAA) on his running plays, the highest single-game total by any quarterback over the past five seasons. Even more remarkably, he did it on just nine carries.

The big game Sunday was just another in a string of strong performances -- since the start of Week 8, no player has a higher Total QBR than Wilson (87.9). That's due to his performance on deep throws and his ability to avoid turnovers.

Since Week 8, only Robert Griffin III (1) has fewer turnovers than Wilson (3) among qualified QBs and Wilson is in the top four in the league in completion percentage (54.8) and TD percentage (9.7) on throws of 10 or more yards.

QUICK HITTERS

• Colin Kaepernick posted an 87.1 Total QBR in Sunday night’s win over the New England Patriots, his fifth straight game with a QBR of at least 60 since becoming the 49ers' starter in Week 11. Kaepernick is second in the NFL in Total QBR this season (79.5) and 49ers backup Alex Smith (70.1) is seventh.

• Aaron Rodgers had an 83.0 Total QBR in Sunday's win over the Chicago Bears, his third straight game with a QBR of at least 80. Rodgers entered Week 15 tied with Drew Brees for most games with a QBR of 80 or higher over the past two seasons.

• Matt Schaub posted a season-high 90.4 Total QBR against the Indianapolis Colts, his highest since Week 10 of last season against the Buccaneers (92.0). With the win, the Houston Texans improve to 17-2 in games in which Schaub has a QBR of 85 or better over the past five seasons.

• Matt Ryan had a 96.2 Total QBR in Sunday's win over the New York Giants, his third game with a QBR of at least 95.0 in 2012. That's tied with Tom Brady for the most such games in the NFL 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 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.
