NFL Power Rankings, Week 2: Packers vault into top three - NFL.com

The unknowable nature of a brand-new season makes the Power Rankings an especially volatile place this time of year.

Previous rank: No.

On a night when Patrick Mahomes averaged a pedestrian 6.6 yards per attempt, Tyreek Hill and Travis Kelce were held under 100 yards combined and Clyde Edwards-Helaire finished his first NFL game without a catch, the Chiefs still put up 34 points in an easy win over the Texans.

Previous rank: No.

Lamar Jackson finished 9-of-10 for 180 yards on throws of 10 yards or more downfield, according to ESPN.

Previous rank: No.

Davante Adams, of course, who tied a franchise record with 14 catches, racking up 156 yards and two scores in the process.

Previous rank: No.

Big plays with his legs (57 yards, TD), a career-best passing day (312 yards, two scores) and -- yes -- a pair of lost fumbles, both on the opponent's side of the field.

Allen also airmailed a gimme TD to John Brown that would have put New York away in the fourth quarter, but on balance, the day was a successful one for both the Bills and their polarizing third-year quarterback.

Malcolm Brown was the rushing star, with 79 yards and a pair of scores from close range.

Cowboys fans will spend the week debating Mike McCarthy's doomed decision to pass on a game-tying field goal in favor of a fourth-and-3 attempt in the fourth quarter.

Jacobs piled up 139 yards from scrimmage and scored three times in a 34-30 win, outproducing Christian McCaffrey in a game featuring two of the league's top young running backs.

The Raiders' defense showed it still has much work to do, but credit is in order for the game-clinching fourth-and-1 run stuff by Clelin Ferrell and linebacker Cory Littleton late in the fourth quarter.

Melvin Ingram's fourth quarter interception on a Joe Burrow shovel pass was a thing of beauty.

2 overall pick came to life and threw three touchdown passes in the fourth quarter of a stunning comeback win over the Lions.

This marked the Bears' first comeback from a deficit of 17-plus points entering the fourth quarter since 1998, according to NFL Research.

Matt Ryan threw for 450 yards and two scores.

Things were even more distressing on the other side of the ball, where Baker Mayfield finished with an ugly 4.8 yards per attempt (the dreaded Gabbert Zone) and Odell Beckham Jr.

finished with 22 yards on 10 targets.

You need a foot on fourth down with the game on the line and you use Christian McCaffrey ...

Previous rank: No?

Just a horrendous setback for the Lions, who melted down in the fourth quarter and allowed a Bears team led by Mitchell Trubisky to steal a win in the opener at Ford Field.

Allowing Trubisky to throw three touchdown passes in the fourth quarter was bad; D'Andre Swift's egregious drop as he backpedaled into the end zone in the final seconds was supernatural in its ghoulishness1

Previous rank: No?

The 27-20 win over the Colts featured opportunistic play by the defense (two key interceptions) and beautifully efficient play by Gardner Minshew, who finished the day 19 of 20 for 173 yards and three scores.

Previous rank: No.

The star running back finished with 6 yards on 15 carries against Pittsburgh's swarming front seven.
