HENDERSON, Nev. (AP) — Las Vegas Raiders quarterback Derek Carr likes to do most of his bonding and chemistry building with teammates prior to the start of each season. Informal workouts, inviting them to his house, personal conversations. Anything that eases the transition from offseason to training camp. With Andre James stepping in as the starting center this season, it was Carr who got an invite from the guy who will be snapping the ball to him hundreds of times this season.
