Usually the week after a losing effort, the mood in the New York Giants locker room is grim.Not so much so this week, however, as they prepared for their rematch against the Dallas Cowboys, a team they lost to by 10 points in the first meeting when the game slipped away in the fourth quarter.Yeah, we did some good things [against Dallas], Giants quarterback Eli Manning told reporters. Theyre a good team. They have a good offense, they score a lot of points, [and] their defense is physical, plays fast and has not given up many points.Weve got to do a good job offensively playing smart. Weve got to eliminate the turnovers. We feel we can move the ball and score some points on them.The fact that the Giants played Dallas so tightly last time and that they are coming off another almost win against San Francisco likely has Manning believing that if they are able to eliminate the constant stream of mistakes, their luck can change.I thought we played hard last week; we competed our tails off, he said. Offensively, we competed. We didnt get down. I didnt play wellwe had turnovers and it looked grim at timesbut we kept fighting and made some big-time plays, especially in the fourth quarter.Guys were fighting, guys want to win and guys believe in this team. The message is getting across; its just obviously the execution has to get better, he added.Of course, the Giants have been saying the same thing for weeks. While the execution does improve in one area, another area usually takes over as the catalyst for the breakdown.So why is there optimism that this might just be the week the Giants snap out of their five-game skid'"We still have something to play for," defensive end Jason Pierre-Paul told reporters. We made it hard for ourselves in this predicament we're in right now. We can dig ourselves out of it by winning all these. We have six games. Just win them. I think we can."Again, talk is cheapto expect the Giants to say anything to the contrary about being able to win would be like expecting the skies to open up and start raining hundred-dollar bills.Assuming they are ready to stop playing sloppy, mistake-filled football, here is a look at five players whose performances can ensure the quest to run the table begins.
