Manning ended up playing until late in the second quarter before handing over the reins&#8212;and another Giants blowout lead&#8212;to Carr. The Giants extended their first-possession scoring streak to five games, sending Ahmad Bradshaw into the end zone for his first touchdown of the year. The Giants proceeded to score touchdowns on each of their next three drives as well: Bradshaw scored again on a 19-yard rush; Manningham caught a 30-yard touchdown pass to open the second quarter; and, following a red zone fumble by Oakland quarterback JaMarcus Russell, Nicks added a 9-yard touchdown reception. In the third quarter, Carr himself ran 12 yards for his first rushing touchdown since leaving the Houston Texans. The Raiders were held to just 7 first downs on the day, their only touchdown coming on the heels of a muffed punt by Moss. The win handed the Giants their first 5-0 start since their Super Bowl-winning year of 1990.
