Exhibit A of parity in the NFL: Eli Manning and the New York Giants. This is a team that hadn't played well in weeks, while Manning had been plum awful. He'd averaged 177 yards per game in his last three outings with no touchdowns and four interceptions. So what does Manning do on Sunday night? Throw three touchdown passes and dominate the Packers' defense. Last December, New York was 6-6, in a tailspin, with almost no hope for the playoffs. What did they do then? Win the Super Bowl. The chasm between the good and bad clubs is not a chasm at all, with the difference in quality often being razor thin. Don't forget: This Packers team absolutely demolished the Texans in Week 6 and brought a five-game winning streak into Sunday night. The NFL truly is week to week, but Big Blue knows what weeks to turn it on.
