Defense Wins Championships — But Health Determines Who Gets There
In the NFL, a dominant defense can be the difference between a playoff run and an early offseason. Strong defensive play disrupts opposing quarterbacks, limits explosive plays, and creates game-changing turnovers. But even the best schemes crumble when injuries hit key personnel as we saw with the Detroit Lions playoff run in the 2024 NFL season.
As we approach the 2025 season, Sports Injury Central’s SIC Health Score Ratings reveal which defenses are entering the year most at risk.
According to the latest data, three high-profile teams — the Miami Dolphins, Buffalo Bills, and Dallas Cowboys — rank among the least healthy defensive units in the league.
Each is dealing with lingering injuries, rehabs, and depth concerns that could impact performance from Week 1 onward.
1. Miami Dolphins — SIC Health Score: 79.4
2. Buffalo Bills — SIC Health Score: 81.7
3. Dallas Cowboys — SIC Health Score: 81.9
The 2025 NFL season will test every team’s depth and resilience, but for Miami, Buffalo, and Dallas, defensive health could make or break their championship hopes.
