Just one week after defensive coordinator Jim Knowles reportedly left the Buckeyes for a job at Penn State, Ohio State offensive coordinator Chip Kelly is reportedly leaving Columbus for the same position with the Las Vegas Raiders, according to reports from ESPN and 247Sports. Jerry Emig, the sports information director for Ohio State football, was unable to verify reports of Kelly’s departure. 📸 Ohio State offensive coordinator Chip Kelly speaks to the media during Media Day at the Sheraton Grand Los Angeles Monday before the Rose Bowl Game Jan. 1.
