The Detroit Lions limped to the finish in the 2025 season, and failed to make the playoffs. In the end, the biggest reason was due to some of the inconsistencies and troubles on the defensive side of the ball.
Detroit had plenty of key players on the sideline for the last few weeks of the year, and it led to their eventual downfall. They couldn't get enough stops at key moments to win close games, which is why they missed on the postseason.
After the season, the disappointment could lead to a major soul-search in terms of scheme or plan.
