The Kansas City Chiefs are the NFL’s only remaining undefeated team after a 27-20 win over the Las Vegas Raiders on Sunday.

They also already made two big trades during the season to get wide receiver DeAndre Hopkins and tight end Josh Uche.

Now that we’re nearing the halfway point of the league, it’s probably time to start asking the question we always ask teams that go unbeaten for so long – can they go unbeaten?

Given the history of the NFL, the answer to that question is very likely a resounding “no.”

Only two teams in the modern era have ever gone an entire regular season without losing a game (the 1972 Dolphins and the 2007 New England Patriots), while only one of them (the Dolphins) has gone perfect through a Super Bowl run Bowl.

It’s nearly impossible to go undefeated and chances are someone along the way will catch the Chiefs. Probably more than one team.

But which team could that be?

Of the remaining nine games, five opponents currently have a winning record, a list that includes Buffalo, Los Angeles (Chargers), Houston, Pittsburgh and Denver.

Three of those games (Buffalo, Pittsburgh and Denver) are on the road and are considered extremely difficult games. Buffalo will be a challenge because the Bills and Chiefs always play close games and the Bills have an MVP leading the way in quarterback Josh Allen.

The Steelers and Broncos both boast elite defenses, with the Steelers now finding some consistency on offense with the arrival of veteran quarterback Russell Wilson.

Aside from the schedule, there is one other key point to make here. As good as the Chiefs record is, and even though they are back-to-back Super Bowl champions, they haven’t really looked like we expect them to, especially on offense.

Quarterback Patrick Mahomes has more interceptions than touchdowns, their wide receiver room has been hit hard by injuries and they aren’t scoring like a typical Andy Reid team.

As true as all of this may be, the Chiefs have completely reinvented themselves as a football team in recent years and no longer rely on a high-powered, pass-first offense to simply outrun teams. They win with a dominant defense led by defensive lineman Chris Jones, run the ball effectively and keep the game close enough to give Mahomes a chance to win late. The formula worked well for them a year ago and it has worked the same way this season.

There’s a lot to be said for a team that can shut down any opposing offense and let an all-time great quarterback make big plays at the end when needed. The Chiefs are great at it, and the sooner football fans accept that this is how they win now, the sooner everyone can be more reasonable about how they play.

They don’t play dumb. They’re just a different type of team that wins in a different way. It works.

Whether or not it works well enough to keep them undefeated remains to be seen.
