NFL Power Rankings: Hottest and Coldest Teams After Sunday's Action

While several teams exploded out of the starting gate in Week 1 of the 2013 NFL season and secured high spots in the power rankings, others were lethargic.

Here are the hottest and coldest teams in the league after the first week of the season.

Hottest

3. Kansas City Chiefs

Kansas City boasts the highest point differential in the NFL thus far (+26). The team deserves praise considering that it finished with the worst record in the league last season. The fact that they achieved this feat against the lowly Jacksonville Jaguars is what keeps the Chiefs from being higher on this list.

2. San Francisco 49ers

San Francisco didn't blow out the Green Bay Packers, but a victory by the score of 34-28 against a team it may face again in the playoffs cemented the former's standing as a Super Bowl favorite. Colin Kaepernick's monstrous day—412 passing yards and three touchdowns—played a key part in the 49ers' No. 2 ranking.

1. Denver Broncos

Denver boasts the second-highest point differential in the NFL thus far (+22), and it achieved such, not against a cellar dweller, but against the defending Super Bowl champion Baltimore Ravens. Peyton Manning was even more dominant than usual, throwing for 462 yards and a mind-blowing seven touchdowns. If it's possible to lay claim to being the Super Bowl favorite after one week, the Broncos did it.

Coldest

3. Cleveland Browns

Brandon Weeden threw three interceptions in a 23-10 thrashing at the hands of the Miami Dolphins. Thank goodness he's only in his second season and has time to develop into a respectable starting quarterback. Oh wait, he turns 30 years old next month—never mind.

2. Pittsburgh Steelers

Pittsburgh's offense only managed to put seven points up on the board against a Tennessee Titans team that is one year removed from allowing the most points in the NFL. Adding insult to injury, Ben Roethlisberger was sacked five times and the Steelers lost Pro Bowl center Maurkice Pouncey for the year to a torn ACL. They also gained just 32 rushing yards and lost LaRod Stephens-Howling for the year to a torn ACL as well.

1. Jacksonville Jaguars

Blaine Gabbert threw as many interceptions as the Jaguars scored points against the Chiefs in Week 1. Jacksonville is in for a long season if it can't even compete with the team that picked first overall earlier this year.
