Against the Jets, the Redskins were without three Week 1 offensive line starters in Shawn Lauvao, Trent Williams and Kory Lichtensteiger. The performance was uneven, but it wasn't just the backups that struggled.
Pro Football Focus graded out the Week 5 loss in New York, and found that rookie Brandon Scherff played his worst game of the year. From PFF: "Scherff received by far his worst overall grade of his career, mostly due to pass blocking struggles (a sack, two hits, four hurries allowed)."
With every starter on the left side of the line lost to injury, perhaps it's not a surprise Scherff struggled on the right. Also, backup center Josh LeRibeus struggled, but the bulk of his errors came in run blocking. One pleasant note from the Redskins O-line was the play of backup left tackle Ty Nsekhe. Sunday's loss in New York marked the first ever start for Nsekhe, a 6'8" mountain of a man with very limited NFL experience, and generally, he performed well. From PFF on Nsekhe, "subbed in admirably at LT, receiving the highest and only green overall grade (+1.4)."
Going through the rest of the PFF grades seems a bit uneven. Bashaud Breeland was one of the few bright spots Sunday, with two recovered fumbles and an interception, though PFF also noted Breeland was "targeted six times and allowed four catches for 58 yards and two TDs."
The grades on Kirk Cousins, obviously, weren't great. Of five throws that went more than 20 yards in the air, Cousins completed zero, except one he completed to a Jets defender.
PFF also determined Ryan Kerrigan played his worst game of the year, as well as Dashon Goldson and Perry Riley. While Riley certainly struggled and Kerrigan was mostly silent, Goldson had a number of big hits and added to the physicality of the defense.
