Everyone expected the San Diego Chargers and Houston Texans to win their respective Week 2 contests, but what about everyone else?
Sunday's slate featured a handful of baffling victories. They made the day's NFL action exciting to watch, but they also created a few long plane rides home.
Let's check out Sunday's most surprising results.
Panthers Defeat the Saints
Carolina's victory over New Orleans may not shock some of you, but it should. The Saints are a prideful organization, and an 0-2 start didn't seem like a likely scenario.
The Panthers didn't look very good against Tampa Bay in Week 1, but they made a quick turnaround. Cam Newton was back to his old self carrying the offense and driving them down the field. He finished with 324 all-purpose yards and two touchdowns.
Defensively, the Panthers still have a lot of work to do. They allowed nearly 500 yards of offense, and the defense is still the team's weakest area, but that doesn't take away from the magnitude of this victory.
Newton's sophomore season got off to a rocky start, but he steadied the ship on Sunday. There isn't a more encouraging sign for the Panthers organization.
New Orleans will head back to the drawing board as it looks to avoid a tremendous falloff this season.
Cardinals Defeat the Patriots
Stephen Gostkowski's wide-left miss on the potential game-winning 42-yard field goal sealed Sunday's most stunning upset.
Arizona—the team with no reliable quarterback—upset Tom Brady and the mighty Patriots. It still sounds weird.
The score was 6-6 at halftime, but you had to be waiting for the Patriots to break out. Aaron Hernandez left the game with an ankle injury in the first quarter, but that shouldn't even the playing field between these two squads.
But it did. The Cardinals sacked Brady four times, obviously impacting his performance with their incessant pressure. That's really the only way to beat Brady, and they made it happen.
New England gained 387 yards, but it had to work for every inch. The Pats only averaged five yards per play, playing right into Arizona's hands.
Kevin Kolb only had 140 yards for the Cards, but he didn't turn the ball over. He let his defense do the work and relied on 105 rushing yards.
This is a signature win for Arizona, and it could provide a building block moving forward. The Patriots will play Baltimore in Week 3 in what should be an extremely interesting matchup.
Seahawks Defeat the Cowboys
Marshawn Lynch and Russell Wilson worked in perfect harmony on Sunday. Seattle's 27-7 victory is shocking after Dallas' decisive victory over the Giants in Week 1.
Lynch, Wilson and the Seahawks' defense made this one happen. Seattle possessed the ball for nearly 10 more minutes than their counterparts. That was made possible by Lynch's 122 yards and Wilson's 15-of-20 performance.
Seattle doesn't have a dynamic offense, but Pete Carroll brings toughness to this team. It is a scrappy bunch, and the Cowboys wilted away from home. Two turnovers didn't help their cause either.
Wilson played exactly as fans had hoped he would. He didn't force anything, played within the offense and ensured that Lynch would carry the load. His 112.7 quarterback rating is exceptional for his second career start.
Dallas had to be feeling good entering this game. It was outstanding versus the Giants in the NFL season opener, but they took a few steps backward here.
