After three consecutive wins, the Dallas Cowboys fell to the Detroit Lions at Ford Field on Thursday night. The Cowboys had secured big wins against the last Super Bowl LIX opponents in the last two games, but were unable to overcome the Lions, suffering a 44-30 defeat.Brian Schottenheimer’s team looked like it was on the path of redemption following a win over the Las Vegas Raiders, Philadelphia Eagles and Kansas City Chiefs. However, the loss on Thursday took them a step backward, and Jason Whitlock openly expressed his disappointment in the team on social media.“I want to apologize for taking Dallas seriously. Won’t happen again. Cowboys defense is embarrassing,” Whitlock wrote on X.The defense was once again where the Dallas Cowboys failed to get it right in Week 14. It conceded a total of 408 yards against the Detroit Lions, averaging 7.2 yards per play. They were unable to stop the Lions in the passing and running game, as they conceded 299 yards in the air and 109 on the ground.The defense, led by Matt Eberflus, has been the major headache for the Cowboys team this season. They've consistently ranked among the worst in the NFL, and after Week 14, they sit 29th in the league in total yards, conceding an average of 378.6 yards and 29.7 points per game.Brian Schottenheimer believes the Dallas Cowboys gave up too many explosive playsIn his postgame press conference on Thursday night, Brian Schottenheimer noted that the Dallas Cowboys gave up a lot of explosive plays that went on to hurt them. With the explosiveness of both offenses, the game was going to go down to defensive performance.“They're fast,” Schottenheimer said. “We got guys that can run, too. I felt like we didn't tackle great. When they got in the perimeter a little bit, I thought they hurt us. We have to look at that, but it's an explosive, explosive football team. I thought Goff played very, very well.“But we just gave up too many explosives – explosive run. Montgomery's explosive run. Big play Jameson Williams after we made it a one-score game. Those are things that we have been doing over the last, you know, three weeks, and we didn't do it tonight.”His comment underscores the defensive struggles of the Dallas Cowboys throughout the season. The loss on the road to the Detroit Lions was a big blow to the team's playoff hopes. They will need the defense to get things right in the closing stages to keep the hope alive.
