In the first quarter, the G-Men drew first blood with QB Eli Manning completing a 33-yard TD pass to WR Plaxico Burress.  In the second quarter, the Rams responded with kicker Josh Brown getting a 54-yard field goal.  New York came right back with kicker John Carney nailing a 33-yard field goal.  St. Louis would answer with Brown kicking a 54-yard field goal, while Carney gave the Giants a 33-yard field goal. In the third quarter, New York increased its lead with Manning completing a 10-yard TD pass to WR Amani Toomer.  In the fourth quarter, the Rams tried to rally as QB Marc Bulger completed a 45-yard TD pass to WR Torry Holt.  Afterwards, the Big Blue pulled away with Manning's 18-yard TD pass to RB Ahmad Bradshaw, DE Justin Tuck's 41-yard interception return for a touchdown, and Bradshaw's 31-yard TD run.
