The Los Angeles Chargers have one of the least productive offenses in the NFL five games into the Jim Harbaugh era. And highly paid quarterback Justin Herbert is averaging just 163 passing yards per game. The Chargers will try to rev up the attack on Monday night when they face the struggling defense of the Arizona Cardinals at Glendale, Ariz. The Cardinals (2-4) are tied for 27th in scoring defense by allowing 27.2 points per game. Arizona has allowed 34 or more points on three occasions, including last week's 21-point loss to the Green Bay Packers. So perhaps the opportunity is there for Los Angeles (3-2) to get its offense moving.
