Often in this space well explore the work of someone who had an exceptionally poor performance QBR-wise, or look at why an opponent adjustment may be helping or hurting a QBs numbers. So why are we looking this week at Detroit Lions QB Matthew Stafford, who had an above-average opponent-adjusted QBR of 66.1 in Sundays win over the Eagles? The reason is that Stafford also happened to possess the highest NFL passer rating of the week at 135.0. Lets take a look at what differentiates Total QBR from Staffords traditional passer rating:Dont forget about the fumbleStaffords passing numbers (19 of 25, 180 yards, 3 TD) last week were fairly impressive. He completed 76 percent of his attempts and threw for three scores without an interception -- all good things. But one area the NFL passer rating fails to account for is when a QB fumbles, yet fumbles are often a big part of the picture of a quarterbacks day.Stafford was responsible for only one turnover, a fumble lost, but it was a potentially costly one. With the Lions up by four and operating at their own 12-yard-line midway through the third quarter, Stafford lost control of the ball while trying to maneuver within the pocket. Officially, the play is recorded as a sack, and the fumble was recovered by the Eagles at the 16, setting them up with a chance to pull within a point with a field goal or take the lead. To put it in terms of their win probability, Detroit went from a 62 percent chance to win before the play to a 50 percent chance after -- a loss of 12 percentage points.Staffords QBR fell from 90.5 to 81.0 on the play though his NFL passer rating was unchanged, underscoring the incomplete nature of the latter metric.Sacks matter tooIn addition to the aforementioned sack-and-fumble, Stafford took three other sacks. The first came on the play just before the lost fumble. That, along with a damaging unsportsmanlike conduct penalty on Anquan Boldin, is what helped set the Lions back to their own 12.Staffords other two sacks both came on third downs in the fourth quarter. The first turned a third-and-7 at the Eagles 38 (on the verge of field goal range) into a fourth-and-16 and a punt, dropping his QBR from a 76.5 before the play to a 67.5 afterward. His final sack came on a third-and-goal from the Eagles 5. Not nearly as detrimental as the lost fumble or moving out of field goal range, but it also wasnt a positive and did make the ensuing field goal attempt slightly more difficult for his kicker.None of these plays were accounted for in his NFL passer rating.How penalties improved Staffords numbersPenalties are one area NFL passer rating overlooks and QBR accounts for, and in this case it was actually beneficial to the latter number for Stafford. He was able to draw a defensive offsides call and a pair of defensive pass interference flags, and while none were huge gains for him, QBR does account for these plays.In the end, the largest differentiators between Staffords QBR and his passer rating were the four sacks and the turnover. If we look at just his 25 passing attempts, his raw QBR would have been an 81. But losses incurred from those damaging plays get us to his final number of 66.1, highlighting the magnitude negative plays can have on a game.A look at Staffords week-to-week progression in the QBR realm: T.
