COSTA MESA, Calif. -- On the opening day of the Los Angeles Chargers' training camp, edge rushers Joey Bosa and Khalil Mack kneeled next to each other on the sideline.
When defensive lineman Joe Gaziano rumbled into the end zone with an intercepted pass, Bosa and Mack sprang to their feet to join in celebration then returned to the sideline, stood hip to hip and resumed conversation.
"I just love to have a guy like that to lean on, ask questions, whether it's about football or just life," Bosa said about Mack, whom the Chargers acquired via trade with the Chicago Bears in March.
