NFL Power Rankings Week 4: Analyzing which undefeated team is the best?

#2 – Las Vegas Raiders

Las Vegas Raiders quarterback Derek Carr

Next week: vs. Los Angeles Chargers

Derek Carr leads the NFL in passing yards after three weeks, averaging more than 400 yards per game. The Las Vegas Raiders quarterback had his struggles in Week 1 against the Baltimore Ravens, but since that overtime win in the opener, Carr and the Raiders have grown in stature and become a force to be reckoned with.

Jon Gruden's team was expected to succumb to defeat against the Pittsburgh Steelers in Week 2, but a shock 26-17 win sent the NFL a message of what they are capable of. In Week 3 against the Miami Dolphins, the men in silver and black lived dangerously at times but ultimately did enough to seal another overtime victory.

Receivers Henry Ruggs Jr., Bryan Edwards and Hunter Renfrow have stepped up this season, while Peyton Barber has been influential in the running game. While there are question marks over their pass defense, this Raiders offense is energetic and they have a solid chance of beating the Los Angeles Chargers in Week 4.

#1 – Los Angeles Rams

Los Angeles Rams quarterback Matthew Stafford

Next week: vs. Arizona Cardinals

Matthew Stafford was always capable of being a dominant force. He's just never had Los Angeles Rams head coach Sean McVay by his side and one of the league's most fearsome defenses helping his cause.

The former Detroit Lions quarterback cranked up his MVP bid to maximum volume by knocking off the defending champion Tampa Bay Buccaneers with a stellar performance on Sunday.

After a standard-setting Week 1 display against the Chicago Bears, Stafford was more subdued in a close Week 2 win over the Indianapolis Colts. Still, in Week 3, the veteran quarterback lit up SoFi Stadium with 343 yards and four touchdowns.

Stafford's 75-yard bomb to DeSean Jackson was a highlight, his chemistry with Cooper Kupp (96 yards, two touchdowns) continues to build and the offensive line is doing a superb job of protecting the franchise's prized asset.

Aaron Donald and the rest of the Rams' defensive front will look to stifle Kyler Murray next week and quickly get the ball back in Stafford's hands. The Rams were strong before Stafford's arrival, but now it's hard to see a weakness in this team. Their unbeaten stretch could go deep into the season.
