The NFL sports five unbeaten teams heading into Week 5: the Denver Broncos, the Kansas City Chiefs, the Seattle Seahawks, the New England Patriots and the New Orleans Saints.
The first two are coincidentally locked in the same division, which is the suddenly mighty AFC West. The Broncos are leading the division thanks to their massive point differential favouring them; their 179 points are 52 ahead of the next team and more than double that of the Patriots.
The Chiefs and Saints are surprises on some level because both of them had poor 2012 seasons; the Chiefs were 2-14 and the Saints were 7-9. That wasn't due to a lack of talent, but both teams now have different coaches from the Andy Reid hire and the return of Sean Payton from suspension.
What a difference.
Meanwhile, nobody is surprised the Patriots are still contending despite the loss of their four best pass receivers from last year. There's a short list of unquestionable things in life: life, death, taxes and Tom Brady plus Bill Belichick equals a Super Bowl contender.
The Seahawks have been impressive in two of the biggest "look at me" wins of the season with their thumping of the San Francisco 49ers in Week 2 and their ridiculous come-from-behind win against the Houston Texans this past week.
All have their merits, but who are the best? Let's break down the list.
