EAST RUTHERFORD, N.J. -- Trent Dilfer became the latest quarterback to suffer the wrath of Osi Umenyiora, Michael Strahan and the New York Giants' defense.
Umenyiora scored on a 75-yard fumble return and the defense helped to account for 24 points as the Giants won their fifth straight with a 33-15 victory over the San Francisco 49ers.
The Giants' dynamic four-end defense dominated the NFL's worst offense. New York (5-2) forced four turnovers by the 49ers (2-4) and sacked Dilfer six times while Alex Smith rested his ailing shoulder.
Strahan had his biggest sack performance since 2003, collecting 2 1/2 against his former defensive coordinator, current 49ers Coach Mike Nolan.
