To me, the Patriots are the team I'm most worried about. They have potentially an elite tight end (if healthy), an all around good defense, and an elite QB that's had a history of beating Peyton in the playoffs.
I could see the Colts and Ravens peak as the season goes on. The Texans and Bengals should be playoff teams, despite mediocre QB play
And then there's teams like the Dolphins and Chiefs, that are both 3-0, but both have a lot to prove before they're seen as legit.
The Chiefs beat the Cowboys by 1 point, at home and they're really the best the AFC has to offer? If so, hard to see Denver not being in the Super Bowl
