Chip Kelly said the opportunity to finally work alongside new Raiders head coach Pete Carroll after the pair had orbited each other as adversaries in previous jobs was a chief reason for his return to the NFL.

Chip Kelly said leaving Ohio State to become the Las Vegas Raiders' offensive coordinator allowed him to return to the highest-level of the sport.

Kelly, 61, is reportedly becoming the highest-paid offensive coordinator in NFL history at $6 million a year. The Raiders will mark his third stop in the NFL and his first as an OC.
