Bears hire Martz as offensive coordinator

The four coaches who followed Martz in St Louis have combined for a 18-51 record.

Ron Turner was fired as offensive coordinator after Chicago's 7-9 season.

Martz, 58, went on to serve as offensive coordinator with the Detroit Lions in 2006-07 and the San Francisco 49ers in 2008 after leaving the Rams.
