What figured to be one-sided wins for the Chicago Bears and Green Bay Packers turned out to be close games while Denver, Miami, Atlanta, Pittsburgh and Oakland won by double-digit margins as slight underdogs or modest favorites. That’s the kind of unpredictable Sunday it was in Week Eight of the National Football League season, although the New York Giants-Dallas Cowboys encounter in Arlington, Texas, was as wild and woolly as you might expect.

Chicago needed a last-play field goal to extend its winning streak to five games with a 23-22 win over the Carolina Panthers. Green Bay let Jacksonsville, a 17-point underdog, hang around before the Packers pulled off a 24-15 win, their third in a row. The Giants also hung on to win over Dallas, 29-24.

Atlanta (7-0), the NFL’s only unbeaten team, had an easier time than expected, jumping on the Eagles early in a 30-17 win in Philadelphia.

Miami and Oakland won division games on the road in the AFC while Pittsburgh swatted away the Washington Redskins and rookie quarterback Robert Griffin III in easy fashion.
