Now they play Sunday at Minnesota, and there is little reason to think they are on the verge of turning things around and upsetting the Vikings.
They took a 10-0 lead over the Vikings on Sept. 20, but they blew it and lost, 27-13. Despite playing the Vikings close twice last year, they lost both games en route to the NFL's first 0-16 season.
In fact, they have lost 14 of their last 15 games against the Vikings — and 11 consecutive games at the Metrodome. They have lost 30 of their past 32 games overall.
To put that in perspective, the Tampa Bay Buccaneers, who began their existence by losing an NFL-record 26 consecutive games in 1976-77 went 4-28 over their first 32 games.
If the Lions lose Sunday, the NFL will see its first 2-31 stretch since the Houston Oilers slid so badly from 1982-84.
No wonder there is talk of morale in Detroit.
"Morale's always an issue on a football team," coach Jim Schwartz said. "Emotion means more in the game of football than in any other sport. This is a team game, and this is a physical game, so you need emotion. Anytime you lose, morale becomes important. When you win, morale's important.
"It's our job to stay resilient. It's our job to see this job through, and we're going to do that."
It's not going to be easy.
Not after rookie quarterback Matthew Stafford threw five interceptions at Seattle, still dealing with effects from his right knee injury. Not with linebackers Larry Foote (knee) and Ernie Sims (hamstring) among the injured. Not with Vikings quarterback Brett Favre settling in with all the talent on his new team.
Stafford and his coaches have said the knee has not been a factor in his performance. But pressed, they say he is not 100 percent.
"I made some bad throws," Stafford said. "But I just need to get used to ... It was only my second game back in a month, and I'm trying to get the strength back more than anything. It's not a fear of injury or anything like that. It's just getting back to playing strength, I would say."
Foote's status is unknown. Schwartz said Monday that Sims' injury had "the potential to be significant," language he usually reserves for long-term injuries. Sims sounded doubtful he would be ready at Minnesota but hopeful he would return relatively soon.
"My body tends to heal up pretty quick," Sims said. "You ask anybody in this locker room. I feel like I'm one of the toughest people on this team. I can play through a lot of injuries."
As for Favre, well, he has been even better than he was in the teams' last meeting, Sept. 20, when he was just breaking in with his new team. And the Lions have struggled to stop quarterbacks of all stripes. Seattle's Matt Hasselbeck posted a 91.1 rating Sunday, and that was the second-worst a starter has posted against them this season.
At 1-7 halfway through their season, the Lions are a mixed bag at best.
"Are we happy where we are? Absolutely not," Schwartz said. "Do we have a long way to go? Yes, we do. Are we working? Sure. Are we seeing positive signs? Yeah. Are we seeing inconsistencies? Yes. Are there changes to be made still? Yes.
"To label us happy or unhappy or anything else — we have work to do every Sunday, and we're not there yet."
