The 25-year-old had a spectacular 2022 campaign, recording 48 quarterback hits, two forced turnovers, a league-high 18.5 sacks, 51 tackles (19 for loss), and other impressive stats. He was the 2019 Defensive Rookie of the Year and a three-time member of the Pro Bowl.
He has recorded an astonishing 43 sacks over the course of four seasons and 51 games—an ACL tear in Week 2 of the 2020 season robbed him the remainder of that season. One of the NFL's most important defensive players is Bosa. He is now compensated accordingly.
According to ESPN's Adam Schefter, the San Francisco 49ers and the standout edge-rusher reached a five-year, $170 million deal agreement on Wednesday.
Last April, the Niners exercised Bosa's fifth-year option, locking him into a deal that will keep him with the team until the 2023 season. But they always felt that keeping him behind bars for a while made the most sense.

General manager John Lynch of San Francisco stated in March 2022 that the team and wide receivers Deebo Samuel and Bosa were discussing future contract extensions.
He told reporters, "We have a plan for each of those men. We'll keep those conversations private, but as I've stated before, those people will be a part of us for a very, very long time. They are outstanding athletes. They form a significant portion of who we are and are fantastic players and people in addition to being at the center of who we are.
One of the team's key offensive playmakers, Samuel, signed a three-year, $71.6 million agreement with the organization last summer, ensuring his future. Its top defensive playmaker followed suit a year later.
Bosa never had any doubts about getting his deal.
When questioned by reporters in early June about his optimism in a new contract with the Niners, Bosa responded, "It's fairly high. Yes, I believe I am rather certain about that.
"I think I'll get what I deserve," he continued.
How close the Ohio State product would get to the four-year, $112 million agreement ($35 million signing bonus, $80 million guaranteed) that T.J. Watt signed with the Pittsburgh Steelers last September was the only thing that remained to be seen.
We now know that Bosa increased his financial fortune. Given his career-long performance while healthy, he will probably be worth every penny of the new contract as well.
