In this Nov. 19, 2006, file photo, Oakland Raiders coach Art Shell works the sidelines during the team’s NFL football game against the Kansas City Chiefs in Kansas City, Mo. Shell was let go by the Raiders following the 1994 season as late owner Al Davis wanted a fresh start for the team for its move back to Oakland. Davis later said he regretted the move and brought Shell back in 2006. Shell had spent his first six years away from the Raiders as an assistant coach but had been out of the profession entirely for five seasons when Davis hired him a second time.
