Write an article that answers the following question: How many more yards Manning needed to match Grossman's throws?
The Giants opened the 2011 season where they had finished the 2010 season, on the road at FedExField against their division rival Washington Redskins to mark the tenth anniversary of September 11, 2001; both teams' cities were attacked by the terrorists that day. New York had not lost to Washington in the regular season in their last six meetings, but fell in this meeting 28-14. After scoring two first-quarter touchdowns and taking a 14-7 lead, the Giants failed to score again. A Ryan Kerrigan interception return in the third quarter put the Redskins in front and they added an insurance score in the fourth quarter when Rex Grossman found Jabar Gaffney in the end zone. Grossman threw for 305 yards and two touchdowns, while Eli Manning threw for 268 with the one interception.
