Khalil Mack contract: Details on Chargers' free-agency splash

The Los Angeles Chargers got a fan wishlist item out of the way early in free agency, signing Khalil Mack to a one-year contract extension worth $18 million. 

At the time, the biggest detail reports offered up was that the contract was fully guaranteed. Not a surprise—the Chargers had more than $90 million in cap space to play with at the time, so it sounded like a nice deal for both the player and team. 

Roughly a week into free agency, we’ve got more details on the contract, though. According to MMQB’s Albert Breer, Mack’s contract carries a $10 million signing bonus and an $8 million fully guaranteed base. 

From a team perspective, the Chargers locked in a player who is 34 years old and still very effective right after the departure of Joey Bosa. For Mack, it’s a lump sum of guaranteed cash and he was owed a little bit after agreeing to a restructure last offseason that, among other things, put a no-tag clause on the remainder of his contract.

With Mack’s contract extension done and the details well-known, the Chargers currently sit on roughly $58 million in free cap space. But that number is before fully accounting for new items like the Mekhi Becton signing to protect Justin Herbert. 

Overall, the Chargers indeed wound up taking that $25 million in savings from Bosa’s departure and applied a chunk of it to Mack. It doesn’t prohibit the team drafting help at the area as high as Round 1 – and sets up a pretty interesting situation if Mack and the Chargers do this dance again in a year’s time.
