The LA Chargers are seemingly done making moves this offseason but I would not hold your breath. With $22.3 million remaining in effective cap space, which is the eighth-most of any team in the NFL (per Over The Cap), the Chargers have the wiggle room to make more additions.
There are still the big-name free agents on the market that are going to warrant a multi-year deal. You have the likes of Jadaveon Clowney and Ezekiel Ansah especially who should be signing a multi-year deal with whatever team is interested.
That is not the market that the LA Chargers are in.
