The Los Angeles Chargers are facing significant challenges in their wide receiver unit as they enter training camp. Tre Harris, the promising second-round draft pick, is holding out for a more favorable contract, complicating the team's depth at receiver. Meanwhile, veteran Mike Williams is expected to start camp on the PUP list, raising concerns about his health and availability. This situation has prompted speculation that the Chargers may need to bolster their receiving corps further. With four other players also beginning on the PUP list, including safety Elijah Molden, the Chargers are navigating a challenging start to the season.
