5 Low-Cost Free Agents the Chargers Must Target
3. Calais Campbell, Defensive Lineman
Calais Campbell is a lot closer to retirement than Nelson, but that doesn't mean he's not playing at an incredibly high level.
The 37-year-old probably only has a year or two left in him, but he remains one of the better defensive linemen in the NFL. He was PFF's No. 28 graded edge defender (among 199 graded) in 2023. It's also selling him short to just call Campbell an edge defender.
With his size and strength, Campbell has the versatility to play any spot on the defensive line. And that means even if Mack and Bosa both stick around for the entire 2024 season, Campbell could make a big impact by contributing on the inside.
The Chargers have a real shot at competing if they can fill out their roster well this year, so having a few veteran additions like Campbell would be great to put them in a "win-now" space without having to commit any long-term money.
At the same time, the 16-year vet would also make for a great mentor for any young linemen the Chargers decide to add in the draft too.
