Week 4 was different, however, as fantasy managers finally enjoyed a double-digit performance from the San Francisco 49ers after a bit of a dull start to the season, totaling 22 fantasy points thanks to a six-sack outing where 3x All-Pro LB Fred Warner also managed the second pick-six of his career.
