ESPN's Adam Schefter reported Tuesday that Bosa agreed to a five-year, $135 million deal to remain in Los Angeles.
Per Pro Football Talk's Mike Florio, Bosa will receive $35 million in a signing bonus, a $17 million roster bonus paid Aug. 15 and a $1 million base salary for this season.
Bosa's base salaries in 2021 ($13.75 million) and 2022 ($21.25 million) are fully guaranteed upon signing the contract; his 2023 base salary of $24 million is guaranteed for injuries and becomes fully guaranteed on the third day of the 2022 league year.
The base salaries decrease in 2024 ($15 million) and 2025 ($17 million), but the two-time Pro Bowler will also receive a combined total of $15.36 million in roster bonuses over those two seasons.
Florio also noted that Bosa's $78 million fully guaranteed at signing ranks fourth in NFL history, trailing quarterbacks Matt Ryan ($94.5 million), Kirk Cousins ($84 million) and Aaron Rodgers ($79.2 million).
The Chargers' decision to invest in Bosa for the future makes sense based on the success he's had in his first four seasons. Per Pro Football Focus, Bosa's 22 percent pass-rush win rate since entering the NFL ranks first among all edge defenders.
Since being drafted No. 3 overall in 2016, the Ohio State alum has recorded 82 quarterback hits and 40 sacks in 51 games. He has registered at least 10.5 sacks in three of his first four seasons.
