2015 NFL Power Rankings: Week 5
Week 4 saw a handful of teams pull off impressive road wins. Is our hierarchy turned upside down as a result?
Not exactly, but we did see some interesting developments. ESPN's Power Panel gave the most significant boost to the Rams, who surged from No. 19 to No. 11 after upsetting the previously unbeaten Cardinals. The Giants continued their upswing by beating the Bills, but the convincing victory wasn't a launching pad, as the Giants gained only one spot, moving to No. 15. The Ravens, thanks to an overtime win over the rival Steelers on Thursday night, clawed their way back into the top 20 (No. 19, a three-spot improvement).
Are more positive moves in these teams' futures? St. Louis has the best chance to rise, as Todd Gurley & Co. travel to No. 2 Green Bay this weekend. A Rams victory at Lambeau Field (where the Packers haven't lost since Week 13 of 2013) looks like a long shot, but so was the prospect of winning at Arizona in Week 4.
St. Louis passed that test. Now it will try to spring a second upset, with a top-10 spot the likely reward.

• Vegas Rankings | Football Power Index Rankings | Where Falcons must improve | Team Power Rankings charts since 2002
|How good were the Patriots in their first three games? They have a better points differential (plus-49) than each of the five 4-0 teams.|
|Winning the turnover battle is always a key to winning. The Packers haven't turned the ball over in their previous 159 minutes and 5 seconds of game play.|
|The Broncos lead the NFL with 18 sacks. Even more impressive? Eleven players have recorded at least one sack this season.|
|Sunday's loss to the Rams was Carson Palmer's first since Week 17 of the 2013 season.|
|Andy Dalton is 4-0 and averaging more than 10 yards per pass attempt. The most recent quarterback to do that? Kurt Warner in 2000.|
|Devonta Freeman has seven rushing touchdowns in his past three games. A Falcons running back hadn't scored more than six rushing touchdowns in a season since 2012.|
|The Seahawks have won their past two, but something is still off. They're one of three teams without a rushing touchdown and one of three teams without an interception.|
|The Panthers have an early defensive player of the year candidate. Cornerback Josh Norman already has 4 interceptions, 5 pass breakups and 2 touchdowns.|
|The Jets are 3-1 for the first time since 2010. That was also the most recent time they made the playoffs.|
|Since 2004, the Steelers are 1-7 against the Ravens when Ben Roethlisberger doesn't start (9-2 vs. all other teams).|
|Todd Gurley had more rushing yards in Week 4 (164) than the Rams' other running backs had combined (111) in Weeks 1-3.|
|The Bills have been called for 58 penalties in four games this season, 12 more than any other team. Those penalties have amounted to 428 yards lost, 92 more than the next-highest team.|
|The Cowboys' offense has been fine without Tony Romo and Dez Bryant. But the defense has forced no turnovers and has allowed 438.0 yards in each of the past two games.|
|Location. Location. Location. The Vikings have lost five straight on the road (including Sunday), but have won five straight at home.|
|The Giants have a plus-6 turnover differential, tied for second in the NFL. They haven't finished with a positive turnover differential since 2012.|
|Does Matt Hasselbeck get Thursday's start against the Texans as well? Andrew Luck is injured, and J.J. Watt has sacked Luck eight times in six games.|
|Philip Rivers is completing 70.7 percent of his passes and leads the NFL in passing yards (1,248). That was all without Antonio Gates (suspension), who will make his season debut Monday against the Steelers.|
|What happened to the Chiefs' defense? K.C. has allowed 31.3 PPG this season, tied for worst in the NFL. Last season, it allowed 17.6 PPG, ranking second in the NFL.|
|Justin Forsett had more rushing yards (150) in the Ravens' Week 4 win against the Steelers than he had in Baltimore's first three games combined (124).|
|The offense is improving, but the defense still needs work. Opponents are converting 46 percent of third-down tries against the Raiders, fourth-highest in the NFL.|
|Sunday's win over the Cowboys marked the first time the Saints committed zero turnovers since Week 13 of last season. Protecting the ball is key, as the defense has allowed the most yards per play this season.|
|The Eagles have shown bursts on offense but no consistency. They have been held to three or fewer points in a half in each of their games this season.|
|Keeping Marcus Mariota upright will be key for the Titans following their bye. Mariota has been sacked on 10.6 percent of his dropbacks this season, second-highest in the NFL.|
|Kirk Cousins has only three career starts (out of 13) without a turnover. The good news is that two have come this season, and both have led to Redskins wins.|
|The Browns have scored a touchdown on three of their 11 red zone drives this season (27.3 percent). That makes those two losses by a touchdown or less even tougher to bear.|
|Ill-timed fumbles aside, the Lions don't even have 200 rushing yards as a team this season -- this after drafting a guard and a running back with their first two picks.|
|All of Colin Kaepernick's touchdowns this season (two passing, one rushing) have come with the 49ers trailing by at least 25 points.|
|Brian Hoyer or Ryan Mallett? Does it even matter? The Texans rank last in completion percentage (52.7) and yards per attempt (5.9).|
|Thanks to Robbie Gould's clutch kicking (9-of-9 on FGs this season), the Bears avoided their first 0-4 start since 2000.|
|The Dolphins have been outscored by a league-worst 34 points in the first quarter this season. Their only score in the first quarter this season was a field goal against the Jaguars.|
|The Jaguars had a chance to take the AFC South lead with a win in Week 4, but failed to score after halftime in an overtime loss. It was their 11th consecutive road loss.|
|Jameis Winston and Mike Evans need to get on the same page. Winston is 10-of-28 with three interceptions and no touchdowns when targeting Evans this season.|
