The Las Vegas Raiders have officially hired Chip Kelly as their next offensive coordinator. Kelly led one of the most explosive offenses in college football at Ohio State last season, helping the Buckeyes win the national championship.

The Raiders and Chip Kelly made it official on Tuesday. Word came on Sunday that the Raiders would hire Kelly as their offensive coordinator and the team announced the move on Tuesday afternoon. Kelly joins Pete Carroll’s staff years after they matched up as head coaches on both the collegiate and professional level.

Kelly has 34 years of coaching experience with 30 years at the collegiate level and four as an NFL head coach.
