No pass defense has been worse than the Detroit Lions over the last four weeks. That much is plainly obvious to anyone who has watched the toothless pass rush and soft coverage that has allowed opponents to throw the ball almost at will.

Thanks to NFL Inside Edge, we have graphic representation of just how bad it’s been of late.

The Lions have allowed a QB Rating of 128.7 since Week 7, handily the worst mark in the league. It’s 13.3 rating points worse than the 31st-ranked Oakland Raiders.

For the season, the Lions have allowed a 100.0 QB Rating, which is 23rd. Atlanta is currently 32nd on the year at 113.2. Note that the Falcons have improved of late; they are not in the bottom five from the last four weeks.

One area where the Lions have fallen off: takeaways. They do not have an interception since Justin Coleman picked off Aaron Rodgers back in the Week 6 loss to the Packers.

The Lions’ worst-ever QB Rating allowed for a full season came in the winless 2008 campaign, when Detroit allowed a league-worst 110.8. The records on Team Rankings only date back to 2003, but that Lions figure is the worst-ever. And the current Lions are on pace to shatter it with their abysmal pass defense of late.
