Training camps are in full swing across the NFL, moving past the initial acclimation phase as teams prepare for preseason games. Several key players are facing contract negotiations, injuries, and performance evaluations during this time.

Justin Herbert's foot injury is a concern for the Los Angeles Chargers, potentially impacting his preparation with a new offensive coordinator. Meanwhile, Brock Purdy's interception issues with the San Francisco 49ers may not be as alarming as they seem, as he focuses on testing his limits during practice.

The quarterback competition for the Pittsburgh Steelers has intensified, with Justin Fields gaining momentum ahead of Russell Wilson due to an early injury. Kansas City is also preparing for potential rookie contributions to protect Patrick Mahomes, while Jameson Williams of the Detroit Lions is under scrutiny as he aims for a breakout season.
