Jimmy Garoppolo has been demoted from the starting quarterback role for the Las Vegas Raiders. Aidan O'Connell will serve as the team's new top signal-caller beginning with Sunday's game against the Giants. Garoppolo's move down the depth chart comes after a dismal performance in his return from a back injury. He leads the NFL with nine interceptions at the halfway point of the season and has regressed in efficiency over his past three starts.
