How Detroit kept the early cap numbers low
Base-salary drop: Joseph’s 2025 base salary fell from the scheduled $3.621 million on his rookie deal to the veteran minimum of $1.1 million. New York PostDetroit Football
Option-bonus model: Instead of large base salaries, each future season features an option bonus that prorates over five years, flattening the cap hit while pushing cash into later seasons. Pride Of Detroit
Void years: Four automatic void seasons (2030-33) allow the bonus proration to extend beyond the contract’s active years, spreading nearly $40 million of dead money unless the Lions extend or restructure before 2030. Over the Cap

Bottom line (facts only)
Kerby Joseph’s four-year, $86 million extension sets new financial benchmarks for NFL safeties while keeping Detroit’s cap charge under $6 million through 2026. The Lions achieved the balance by combining a modest 2025 base salary with a series of escalating option bonuses and four void years, deferring the largest hits until 2028 and beyond. On the field, Joseph enters 2025 as the league’s reigning interception leader and, by average salary, its highest-paid safety.
