One game-deciding matchup on Sunday will show if the Commanders addressed a major issue after getting embarrassed last week

The Commanders can't stop big plays

The Commanders' defense has allowed the sixth-most receiving yards in the league so far, and they are one of the worst big-play defenses in the league. The defense has also allowed an embarrassing 20 pass plays that have gone for 15+ yards, which is the second most through four games, and five plays of 40+ yards. Both of those numbers are worse than last year's through the first four games.

Johnston is poised for a massive day if the Commanders' trends on defense continue, and McConkey and Keenan Allen can all get their production as well if you focus on Johnston too much. They have weapons all over the place, and that's not even including running back Omarion Hampton, who has become a force over the last two weeks on the ground and through the air.

Herbert is also the best quarterback they've faced so far, and he's fourth in the league with 1,063 passing yards and seven passing touchdowns. He's making some ridiculous throws downfield despite being pressured on almost half of his throws.

Herbert will have an absolute field day on the Commanders' secondary if they don't change their lack of communication and poor coverage in both zone and man. They will need some help, though, and the defensive line can get pressure on Herbert after disappearing last week against the Falcons.
