Dud: CB Richard Sherman

Sherman usually plays a physical brand of football, but Sunday got a little too physical. The cornerback was called for three pass interferences, all while covering second-year receiver Christian Kirk. The first prevented a potential touchdown, but led to an Arizona field goal. The second put Arizona within five yards of the end zone, and they cashed in with a touchdown two plays later. Sherman has helped the 49ers defense more often than not, but Sunday he did more harm than good.
