It is only fitting that Peyton Manning finished the regular season with his highest single-game Total QBR in the last five seasons. Manning posted a 98.7 Total QBR in the Denver Broncos win over the Kansas City Chiefs, his ninth game this season with a 90+ Total QBR. No other player has more than five such games.

Manning finished the season with an 84.1 Total QBR, the second-highest single-season Total QBR since 2008. Peyton now has three of the top five single-season Total QBRs over the past five years.

It’s worth noting that since 2008 every player that finished the regular season with the highest Total QBR went on to win the MVP award.

Peyton’s little brother was no slouch himself in Week 17.

Eli Manning posted a 99.6 Total QBR in Sunday's win over the Philadelphia Eagles, the highest single-game Total QBR this season and third-highest rating over the past five seasons. Manning's Total QBR never fell below 99.5 the entire game as the New York Giants built an early lead that they did not relinquish.

Eli Manning was 6-of-7 for 116 yards and three touchdowns on the Giants' first three drives to take a 21-0 lead. After the Giants' third touchdown, their win probability jumped to 94.5 percent and never fell below 90 percent for the rest of the game.

Sanchez struggles again
On the other end of the spectrum is Mark Sanchez. He posted a 9.3 Total QBR in the New York Jets loss to the Buffalo Bills. It was his sixth game this season with a Total QBR of 10 or lower, three more than any other player. Among qualifying QBs, no player had a lower Total QBR than Sanchez this season.

To put it into perspective using QB points above average (QB PAA), Mark Sanchez contributed 50.2 fewer points to his team than what an average QB would contribute in the same number of action plays. In other words, an average QB would have contributed 3.4 more points per game than Sanchez in the 15 games that he played.

Total QBR and winning

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.
