The Dallas Cowboys have won six straight games and now have the NFL's best record at 6-1. They made their first big statement a month ago by routing New Orleans in prime time. Last week, they went into Seattle and became only the second road team in the past two years to win at CenturyLink Field. This week, they easily took out the New York Giants in their first NFC East matchup of the season. DeMarco Murray broke an NFL record with his seventh straight 100-yard game and Tony Romo leads the NFL in completion rate (69.2 percent) and has 97.5 QBR on third downs.

It finally seems like the glory days have returned for America's Team after three straight years of 8-8. The ESPN Power Rankings currently have Dallas as the No. 2 team in the league, trailing only the Denver Broncos.

However, a look at their performance over the season to date suggests that the Cowboys aren't quite that good.
