Analysis of NFL Preseason Defensive Strategies

As the NFL preseason approaches, discussions often arise regarding the effectiveness of defensive strategies employed by teams. Analysts suggest that defenses typically utilize simpler schemes during this period, which may not accurately reflect their regular-season tactics.

Data from the 2025 preseason indicates that defenses, on average, displayed a significant difference in coverage usage compared to the regular season. For instance, Cover 1 accounted for 25.6% of preseason coverages, contrasting with 17.6% during the regular season. The Chicago Bears exemplified this trend, significantly altering their coverage strategies from preseason to regular season.

While some teams, like the Miami Dolphins, maintained consistent coverage profiles, others, such as the Jacksonville Jaguars, showcased a marked shift in their defensive approaches. Overall, the findings suggest that while many teams reveal their tendencies during the preseason, a few coordinators intentionally hold back strategies for the regular season.
