In the second quarter, the 'Skins QB Jason Campbell made an 8-yard TD pass to TE Chris Cooley, while kicker Shaun Suisham ended the half with a 47-yard field goal and a 17-3 lead. With the Giants staring at a 14-point deficit, and an 0-2 start to their season, the Giants came out strong to start the second half. In the third quarter, QB Eli Manning finally got the Giants offense turned around and RB Reuben Droughns would score on a 1-yard TD run to cut the lead in half. In the fourth quarter, Droughns rushed again for a 1-yard touchdown, while Manning completed a 33-yard TD pass to WR Plaxico Burress, giving the Giants a startling 24-17 lead against the home team. In the game's final moments, Washington found first and goal at the Giants 1-yard line. New York's defense then proceeded to make a goal-line stand as they stopped RB Ladell Betts from getting into the end zone on 4th down during the final seconds of the game. This goal line stand was known as the initial catalyst of the Giants' Super Bowl season.
