Well, that was fun.
The opening Sunday of the 2013 NFL season was delightfully wild, from Adrian Peterson's 78-yard touchdown run on his first carry of the year to the abysmally wacky battle between the Dallas Cowboys and New York Giants on Sunday night.
It was a chaotic day across the league, and some teams clearly showed more rust than others. And although there are still two Monday night games on tap (Philadelphia Eagles vs. Washington Redskins, Houston Texans vs. San Diego Chargers), let's take a look at the biggest risers and fallers from Week 1.
Teams who moved the most are marked with an asterisk.
1. Denver Broncos (1-0)
The Broncos were the most impressive team in Week 1, beating the defending champion Baltimore Ravens 47-29 on opening night.
If that's not deserving of the No. 1 spot, I don't know what is.
2. San Fransisco 49ers (1-0)
Colin Kaepernick (27-of-39, 412 yards, three touchdowns, zero interceptions) outdueled Aaron Rodgers (21-of-37, 333 yards, three touchdowns, one interception) while leading the 49ers to a 34-28 win over their NFC rivals.
Until someone beats them, the 49ers are the best team in the NFC.
3. Houston Texans (0-0)
The Texans will begin their 2013 campaign tonight against the San Diego Chargers (10:15 p.m. ET).
4. Seattle Seahawks (1-0)
The Seahawks shot themselves in the foot on Sunday, racking up 99 yards in penalties. Luckily for Russell Wilson and Co., they were able to escape Carolina with a 12-7 win.
5. New England Patriots (1-0)
After one of the worst offseasons in NFL history, I'm sure the Patriots are quite happy with their Week 1 win. Tom Brady still needs to build some chemistry with his new receivers, but that will come with time.
* 6. New Orleans Saints (1-0)
Sean Payton's return to the sideline was a success, as the the New Orleans Saints knocked off the Atlanta Falcons 23-17 at home.
Drew Brees put up his typical numbers, completing 26 of 35 passes for 357 yards and two touchdowns. He also threw one interception in the third quarter, but the Falcons were unable to capitalize.
Although they were far from perfect, this was an encouraging performance for the Saints.
7. Washington Redskins (0-0)
The Redskins will begin their season Monday night against the Philadelphia Eagles (6:55 p.m. ET).
8. Green Bay Packers (0-1)
The Packers will be disappointed to start the season 0-1, but there's no shame in losing a tight game to the 49ers. Green Bay will still be one of the top three or four teams in the NFC this season.
9. Chicago Bears (1-0)
The Bears took down the Cincinnati Bengals in their season opener, prevailing 24-21 at home. Brandon Marshall had another monster game for Chicago, catching eight passes for 104 yards and a touchdown.
* 10. Baltimore Ravens (0-1)
The Ravens were embarrassed by Peyton Manning and the Broncos, and they should plummet in the power polls because of it. However, it's still too early to drop the defending champs out of the top 10.
11. Atlanta Falcons (0-1)
Like Green Bay and Baltimore, the Falcons will be just fine this season. They simply ran into a team that was more prepared for Week 1. I'm still expecting Atlanta to be a top-four seed in the NFC.
12. Indianapolis Colts (1-0)
It was closer than they would have liked, but the Colts started the season off with a W after beating the Oakland Raiders, 21-17. Andrew Luck didn't put up huge numbers, but his efficiency (18-of-23, no interceptions) was brilliant.
13. Cincinnati Bengals (0-1)
14. Detroit Lions (1-0)
The Lions didn't start so hot, as they let Adrian Peterson romp 78 yards for a score on his first touch of the season. Things got considerably better from there, though, and the Lions went on to defeat their NFC North rival, 34-24.
15. Kansas City Chiefs (1-0)
The Andy Reid and Alex Smith era started off with a bang, as the Chiefs cruised to a 28-2 win. Of course, it was against the lowly Jacksonville Jaguars, but a win is a win.
16. Dallas Cowboys (1-0)
The Cowboys submitted one of the weirdest performances of Week 1. Somehow, they forced six Giants turnovers and scored two defensive touchdowns but only managed to win by five points.
Either way, I'm sure owner Jerry Jones will take it.
17. Miami Dolphins (1-0)
The Dolphins got nothing from high-profile newcomer Mike Wallace (one catch, 15 yards), and they only produced 20 rushing yards as a team. Still, second-year quarterback Ryan Tannehill was able to lead them to a 23-10 victory over Cleveland.
18. St. Louis Rams (1-0)
Sam Bradford looks to be benefiting from the new talent around him, as he completed 27 of 38 passes for 299 yards on Sunday. He already has great chemistry with tight end Jared Cook, who caught seven passes for 141 yards and two touchdowns in his Rams debut.
19. Minnesota Vikings (0-1)
The Vikings held Calvin Johnson to just 37 yards on three catches. However, four Christian Ponder turnovers and a monster game from Reggie Bush did them in.
*20. Tennessee Titans (1-0)
It wasn't pretty, but the Titans pulled out a solid 16-7 win over the Pittsburgh Steelers. Their defense was excellent, holding Ben Roethlisberger and the Steelers to just 195 yards of total offense.
Unfortunately for the Titans, they'll probably get stomped by Houston next week.
21. New York Giants (0-1)
Eli Manning threw three interceptions, and the Giants running game is in shambles. With the Denver Broncos coming to town next week, the Giants will likely limp to an 0-2 start.
22. Carolina Panthers (0-1)
Cam Newton was suffocated by the Seattle defense, but the Panthers still lost by just five points. With a manageable upcoming schedule (Bills, Giants, bye, Cardinals, Vikings, Rams, Bucs), look for the Panthers to steadily climb up these rankings.
23. Pittsburgh Steelers (0-1)
The Steelers lost their first season opener since 2002. Things don't get any easier for Big Ben and Co., as they travel to Cincinnati next week.
24. San Diego Chargers (0-0)
The Chargers will begin their season Monday night against the Houston Texans.
25. New York Jets (1-0)
The Jets lucked their way into an 18-17 win over the Tampa Bay Buccaneers, so they won't rise too high. But if they can upset Tom Brady and the Pats next week? That's a different story.
26. Buffalo Bills (0-1)
The Bills lost their season opener, but they have to be encouraged about the future. Rookie quarterback EJ Manuel completed 18 of 27 passes for 150 yards, two touchdowns and no interceptions.
27. Philadelphia Eagles (0-0)
The Philadelphia Eagles will start their season Monday night against the Washington Redskins.
28. Oakland Raiders (0-1)
For the first time in years, the Oakland Raiders actually have something to be excited about: Terrelle Pryor. The third-year quarterback racked up 329 total yards (112 on the ground) and gave his team a chance to win late. He threw a pick on the potential game-winning drive, but Pryor's potential is evident.
29. Arizona Cardinals (0-1)
The Cardinals got big games from receivers Larry Fitzgerald and Andre Roberts, but it wasn't enough to overcome Sam Bradford and the Rams.
30. Cleveland Browns (0-1)
The Browns let Brandon Weeden go wild on Sunday, as the second-year QB threw a ridiculous 53 passes on the day. He only completed 26 of those, and his three interceptions were discouraging.
*31. Tampa Bay Buccaneers (0-1)
The Bucs should plummet in everyone's rankings after Week 1. Doug Martin was largely ineffective (65 yards on 24 carries), Josh Freeman completed less than half of his pass attempts, and Lavonte David earned the dumbest penalty of Week 1.
This should have been an easy win for Tampa Bay. Instead, the Buccaneers are 0-1 and heading into games against the Saints and Patriots.
32. Jacksonville Jaguars (0-1)
The Jaguars total number of points in Week 1 (two) matched their win total from last season. That's just sad.
