Why Bengals are NFL's best team

As the Cincinnati Bengals have been a playoff team the past three years, everyone expected that they would be good in 2014. But this good? The Bengals are 3-0 -- the only remaining undefeated team in the AFC -- and rolling into their Week 4 bye.

With an explosive offense, a tenacious defense and the three most complete performances in the NFL, this team has been very impressive. Marvin Lewis, in his 12th season with Cincinnati, has done an excellent job helping his veteran squad through the transition of a new offensive and defensive coordinator. While I picked Seattle and Denver to make the Super Bowl before the season, there's no question that right now, the Bengals are the best team in the NFL.

Here are the biggest reasons:

An efficient offense and improved play from Dalton

I've been very impressed with Cincinnati's offense, beginning with the five men up front. The Bengals' offensive line has allowed zero sacks this season and has given Dalton plenty of time to throw on long-developing routes. Dalton has thrown only one interception, and Cincinnati has zero fumbles.
