The Redskins defense has crashed and burned after a strong start to the season. And a porous rushing defense has played a big part in that decline. In the first five games of the season, the Redskins gave up more than 100 rushing yards once. They were 3-2 and had allowed 30 points in a game just once. But in their seven games since then, the rushing defense results are a mirror image of the early-season numbers. They have allowed fewer than 100 yards just once since Week 7. It’s not a coincidence that they have held an opponent to under 33 points just twice in that span and that their record is 2-5. The futility hit a low point against the Cowboys. In their Week 8 loss to Dallas, Ezekiel Elliott gained 150 yards rushing. He’s one of the best backs in the league and he is capable of doing that against even the better defenses in the league. The performance was not acceptable, but it wasn’t cause for alarm, either.
