GLENDALE, Ariz. -- The Detroit Lions (5-8) beat the Arizona Cardinals 17-3 on Sunday at State Farm Stadium. Here are three things we learned in the victory, just their second in seven weeks.

Yes, the Detroit Lions are still in the playoff hunt. Technically, anyway. Not only did they win, but Philadelphia (6-7), Washington (6-7), Atlanta (4-9) and Tampa Bay (5-8) all lost. Among NFC wild-card contenders, only Green Bay (5-7-1) won, pending tonight’s game between Minnesota (6-5-1) and Seattle (7-5). And the Lions still have games left against Minnesota and Green Bay. In other words, almost everything broke Detroit’s way this weekend, and yes, the postseason is still on the table -- yet the odds of it happening rose to just 1.8 percent, according to FootballOutsiders. That’s up from 0.4 percent last week. Progress?

Darius Slay is still good at football. Nobody thought he was bad, either, but Slay just hasn’t been his usual, shut-down self. He was allowing a QB rating of 106.8 on balls thrown his way heading into the weekend, double what he allowed in his All-Pro campaign in 2017. But Slay was back to his old form in this one, including stepping in front of a Josh Rosen pass and returning to the house for the first touchdown of his career. “It was a really good play by the DB," Rosen said. "He basically sat at the sticks. He made it seem like he was giving them space. It made it seem like he was playing really soft, because it was third-and-long. Right when our receiver broke at the sticks, he just made a really good play. He’s a veteran. That’s why I’ll maybe go away from him next time.”

Jarrad Davis is on the rise. The former first-round pick has been up and down throughout most of his two seasons in Detroit, but really seems to be figuring things out. He’s played some of his best ball lately, and turned in a masterful performance against Arizona. He swept sideline to sideline for a team-high eight tackles, two of which were for loss. He also notched his fifth sack of the season, up from two last year, and added a pass breakup for good measure. It’s no coincidence the Lions defense has been playing better lately, too. Davis is so important to what Matt Patricia is trying to do with this scheme -- and lately, things seem to be clicking into place.
