My point is they have not been tested. Same with the Patriots (I'm a huge Pats fan). I'm honestly afraid of these 7-0 Pats, they're playing the AFC East (Only Pats and Jets have winning records), the AFC South (Not a single team over .500), and the NFC East (best team, NYG, is .500) this season.
They are in no way prepared to play actual teams with well rounded offense and defensive threats IMO. Same goes for the Bengals. They at least have the Cards, Rams and Broncos left on the schedule so they get some real tests before the postseason, but how they match up against those guys will be a look at what kind of team they really are. I think the Pats are gonna march into the postseason 15-1 or 16-0 and fall apart in the AFC Championship game against a wildcard team with a shit record that had experience against some tough teams this regular season.
EDIT: Also health is a big if, especially if Bad Andy shows up to throw some more high balls that result in Marvin Jones (and others) getting ragdolled like yesterday.
