The intent of Total QBR is to isolate each NFL quarterbacks contribution to his teams fortunes as accurately as possible with the data available. It measures nearly every aspect of quarterback play, from passing to designed runs to scrambles to turnovers to penalties. QBR also strives to separate the performance of the individual quarterback from the rest of his team, all in an effort to rate the overall efficiency of each quarterback in the league.One thing it hasnt done, however, is to account for the strength of the 11 players on the other side of the line of scrimmage.But now, QBR accounts for opposing defenses: Quarterbacks who face tougher defenses will have their ratings adjusted upward in proportion to the difficulty of their opposition, and those who face weaker defenses will have their ratings adjusted downward. This is one more step toward gaining a true measure of overall quarterback performance -- and a big step.Heres how the opponent adjustment works. Early in the season, we dont have enough information on how good each defense truly is. It usually takes several weeks of data to have a reasonable estimate of how tough each defense is. So the adjustment starts with an estimate for each defense, which is based on a model of how defensive performance varies from one season to the next. Then, as each week is played, we update that estimate with performance information from each game. The result is an accurate and relatively stable estimate of how tough each defense is for a quarterback to face. Several weeks into the season, the effect of the early estimate becomes very small, and by the end of the season it is virtually nonexistent.Next, we compute an adjustment to each quarterbacks performance based on those estimates of how tough each defense is. We also factor in home-field advantage. Its no surprise that quarterbacks playing at home tend to have an easier time than those playing on the road. These adjustments are made underneath the hood of QBR -- on each quarterbacks share of his teams expected points added (EPA) per play, which factors in nearly all aspects of quarterback play, including passes, scrambles, designed runs, sacks, turnovers and even some penalties. Those EPA rates are also adjusted to correct for performance in garbage time, when the games outcome has effectively been decided.Lastly, those adjusted EPA rates are scaled to produce the final opponent-adjusted QBR, which is a number from 0 to 100. This scale can be thought of as a percentile of game-level performance -- 50 is average and a 99 would be among the best games on record. Quarterbacks dont often get below a QBR of 5 (theyll get benched by that point). On a season level, a QBR of 75 or higher would be elite performance, and 25 would be considered replacement-level performance.Early in the season, the opponent adjustment will have the most impact since many quarterbacks have faced an imbalanced set of opposing defenses. Some examples will help explain how the adjustments affect the ratings.Through Week 3 in 2016, Ryan Tannehills unadjusted raw QBR of 53.0 suggests he has been playing at a league-average level. But his adjusted QBR of 62.2 is significantly higher, highlighting how difficult his opponents have been so far. The Dolphins have faced the Seahawks and Patriots, both on the road, plus the Browns, whose defense so far has been middle of the pack.Drew Brees exemplifies the opposite. Through Monday night, his opponent-adjusted QBR is 52.7, lower than his unadjusted raw QBR of 57.5. His Saints have faced the Raiders, Giants and Falcons, all three in the bottom-third of the league in terms of defensive QBR allowed, with two of three games at home.By the end of the season, most starting quarterbacks have faced an evenly balanced set of opponents, so their adjusted and unadjusted QBRs will be very close. But there are exceptions, and those are the interesting cases. For example, in 2015, one reason the Panthers were able to finish the regular season 15-1 was that they faced a disproportionate number of weaker defenses. The difference between Cam Newtons unadjusted raw QBR of 70.3 and his adjusted QBR of 65.1 (retroactively calculated) reflects the relative weakness of his opponents.On the game level, the adjustments are usually more stark. Matt Ryans recent Monday night game at New Orleans was among the weeks best performances with a raw QBR of 92.4. But because the Saints defense is among the leagues easiest for quarterbacks to face, Ryans opponent-adjusted QBR for that game falls to 87.8.Jacoby Brissett, the Patriots rookie fill-in, had a storybook debut against the Houston Texans, who have one of the leagues most formidable defenses. His raw QBR for the game was 62.1, but after opponent adjustment, it becomes 70.7. The highest-rated game since 2006, when QBR began, is a 99.8 by Colin Kaepernick in the 49ers 42-10 win against the Jaguars in 2013.Jacksonvilles defense was near average that season, so Kaepernicks raw and adjusted QBR are the same. Kaepernick was 10-for-16 with a TD and no interceptions, but this is where QBR and the traditional passer rating diverge. Kaepernick absorbed no sacks, never fumbled, rushed for 54 yards on seven carries, and added two rushing TDs. Remember that QBR is a measure of efficiency, rather than total production, and this game is almost as efficient as it gets.The new, adjusted QBR is now the number youll find under the Total QBR column on the QBR page. The unadjusted QBR is now called raw QBR and is still available for all seasons and games. No player rating system can be perfect, but we think adjusting for opposing defenses is one more step forward for measuring total quarterback performance. Tony Watson Jersey .J.

Gaylord Perry Jersey . - After leading the Saints to a fourth playoff appearance in five seasons, Drew Brees expressed confidence in the direction of his team and, perhaps more importantly, showed a willingness to listen to contract proposals if the team needs his help getting under the NFLs salary cap. Hunter Pence Jersey . A knee to the thigh might have stung him the most, but his sixth straight double-double made up for the brief burst of pain. Brad Fittler medal winner Josh Jackson has put his hand up to take over from the retiring Paul Gallen as the NSW State of Origin captain next year.After he was voted by his peers as this years best Blues player, Jackson has welcomed the possibility of leading them down the tunnel against Queensland next season.Of course, Id absolutely love to do it, Jackson told AAP.But theres a number of other guys there that are more than capable of doing it as well.The fact that there is so many guys there, will make it easier for the person who does get the nod.Jackson is firmly entrenched in the Blues back row after starting all three games on the right edge this season.He has now played six Origin games in a row since his debut in 2015.With Gallen departing and veteran hooker Robbie Farah without a club for next season, NSW coach Laurie Daley is likely to shake up his leadership group.But theres a lot of leaders at their club here already, so hopefully we can create a good culture moving forward. And a successful one too, Jacckson said.ddddddddddddThe Canterbury star also backed under-fire coach Des Hasler to remain at the NRL club despite falling short of an elusive premiership in his fifth-straight post-season appearance at Belmore.The Bulldogs have made two grand finals under his tenure, but were blasted out of this years finals by Penrith in week one.They lost their final four games of the year.I cant see anyone else that could come in and do a better job than Des. Hes the ultimate professional. Hes got the respect of all the players and staff at the club, Jackson said.The Bulldogs second-rower also defended the teams game plan, saying that their forwards-based style of play had provided the plenty of success in recent years.The last six weeks is more individual errors for us more than the structural side of things. Weve had success over the last few years from that structure and the game plan, he said. ' ' '
