The same rings true with a division.What we thought we know about the eight divisions in the NFL heading into the year -- well, Week 1 threw us a curveball.

Let's give a round of applause to the Houston Texans for sitting alone atop of this division after Week 1. Unfortunately, that's not a good indicator of how this division fared as a whole.

The Cowboys did lose to the defending Super Bowl champion , but threw for 403 yards and three touchdowns and the defensive forced four turnovers.

Zach Wilson had a solid game in spite of a nonexistent rushing attack and an offensive line that lost for 4-6 weeks.

The Saints may be challenging the Tampa Bay Buccaneers for division supremacy after all.The Buccaneers still have and all 22 starters back from their Super Bowl championship team. Dallas gave Tampa Bay its best shot, but Brady rallied the Buccaneers to victory. The Carolina Panthers are a much better team with back, and earned a tough victory over a young Jets team.
