In 2024, the Jacksonville Jaguars had one of the worst defenses in the NFL. Despite the presence of obvious talent on the roster, then-defensive coordinator Ryan Nielsen took that talent and ran it into the ground. Nielsen forced his players to gain weight unnecessarily, alienated them with his bad attitude, and in general, seemingly went into the 2024 season with the goal of being fired.
That wish was granted, and Nielsen was replaced by Anthony Campanile. There were expectations that the Jacksonville defense would improve, but just how well they have done so far has gone above and beyond what anyone could have expected.
