Jim Knowles landed at Penn State less than a week after helping Ohio State win the national championship. In those precious days following the College Football Playoff finale, the sought-after defensive coordinator had options from which to choose.

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.
