NFL Week 15 winners and losers: Cardinals, Bucs look terrible; Patriots, Titans give Chiefs a boost

The Week 15 slate was reduced because of COVID-19 outbreaks, with three games postponed to Monday and Tuesday. Still, there were some key outcomes from Sunday's games, even if only one team clinched a playoff spot.

The Green Bay Packers became the first squad in the 2021 season to book their spot in the postseason after taking down the Ravens, 31-30. They also strengthened their claim on the No. 1 spot in the NFC and separated themselves from the rest of the NFL, currently holding the league's best record.

One of their key competitors, the Arizona Cardinals, was expected to clinch a playoff berth but instead suffered a stunning 30-12 loss against the previously one-win Detroit Lions. Another team near the top of the NFC, the Tampa Bay Bucs, lost in historic fashion, with Tom Brady being shut out at home for the first time in his career.
