Through four weeks, the Kansas City Chiefs stand as the NFL's only undefeated team—taking down another playoff contender in front of a raucous crowd at Arrowhead Stadium on Monday night.

The Chiefs showed a little bit of everything against the Redskins, but more so than anything, they showed that they can win in a lot of ways.

This wasn't the opener against the New England Patriots—when most things went right. The Chiefs struggled at times against the Redskins, but they still found a way to come out victorious.

In the end, obviously, that's all that matters.

Now, after the thrilling victory that ended with a rookie kicker nailing a 43-yard field goal with eight seconds left in his NFL debut, there's no doubting it anymore—the Chiefs are the best team in the NFL right now.

And according to the latest NFL power rankings, that idea proves to be a consensus.

The Chiefs are No. 1 in every major power rankings list out there.

Here’s what Elliot Harrison of NFL.com had to say about the Chiefs:

"Top-shelf teams often squeak by in games, win when they probably shouldn't, or get by with partial personnel. Each is applicable to the Chiefs, who -- final score notwithstanding -- narrowly moved past the Redskins towards Week 5. It took a final drive from Alex Smith and the offense to set up the go-ahead field goal.

"Without the benefit of a few Washington penalties in the second half, who knows? Yet, the fact that Kansas City did win -- despite being without three O-line starters, Dee Ford and the kicker -- actually made the performance more impressive. The Chiefs gutted this deal out. Particularly Alex Smith, who showed he can still motor in his 30s."

Here’s what ESPN had to say about the Chiefs:

"Kirk Cousins completed just 58 percent of his passes against the Chiefs on Monday night ... which was still the best by any quarterback against them this season. Kansas City has allowed a league-best 51 completion percentage en route to a 4-0 start."

Here's what Pete Prisco of CBS.com had to say about the Chiefs:

"There is little doubt now they are the class of the league heading into the next quarter of the season."

Here’s what Chris Simms of Bleacher Report had to say:

"The Chiefs are the best team in the NFL right now. The offense is creative—it makes opponents defend all areas of the field—and there are plenty of explosive weapons on that side of the ball. Kareem Hunt's ability to run between the tackles and Alex Smith's aggression in the passing game are taking the offense over the top. Defensively, Kansas City has athleticism, size and speed. The unit did enough to hold off a good Washington offense, and it did so without Tamba Hali and Dee Ford…

Kansas City is the most complete team in football, and the Chiefs' status as the only undefeated NFL team reflects that."

Here’s what Frank Schwab of Yahoo Sports’ Shutdown Corner had to say:

"That was a good win over the Redskins. If Washington is legit, and it looked that way Monday night, Kansas City's wins include at New England, vs. Philadelphia and Washington. And they beat the Chargers, who are better than that 0-4 record. This is going to be a season defined by extreme parity, but right now having the Chiefs No. 1 is the only sure thing (well, that and having the Browns last)."
