Biggest Single-Season NFL Team Declines

Exploring historical examples of NFL teams experiencing significant drops in performance from one season to the next.

The top 3

Top 3 Teams with Largest Win Drop-offs: While specific 'top 3' lists for largest win drop-offs vary, the 1998 Indianapolis Colts (from 13-3 to 3-13) and the 2007 Miami Dolphins (from 1-15 to 11-5, though this is an improvement, the inverse for decline would be significant) are often cited in discussions of dramatic year-to-year changes in win percentage.
Worst Post-Super Bowl Season Records: Teams that win the Super Bowl rarely have a losing record the following season, making significant post-championship declines notable, though specific 'worst' records are less common than general regression discussions.
Teams with Most Consecutive Losing Seasons: The Tampa Bay Buccaneers hold the NFL record for consecutive losing seasons with 14, from 1983-1996, while the New York Jets currently have the longest active streak with 10 consecutive losing seasons (2016-2025).
