Chip Kelly is returning to the NFL as the Las Vegas Raiders' offensive coordinator, a person with knowledge of the decision said Sunday.

With Carroll’s legacy established, the Raiders made sure they got their choices at the coordinator positions. First retaining DC Patrick Graham and then quickly nabbing Chip Kelly weeks after he guided a juggernaut Ohio State offense to a National Championship.

Kelly is returning to the NFL for the second time. He was previously the head coach for the Philadelphia Eagles and the San Francisco 49ers, holding a 28-35 record combined in both stints. Former USC Trojans coach Pete Carroll has plenty of familiarity with Chip Kelly as the two once coached against each other in the PAC-10 conference when Kelly led the Oregon Ducks.
