I think we are still the favorite in the AFC, but there are some legitimate concerns regarding this team.
Most notably is Logan Ryan's massive regression. Ryan went from an excellent CB2 to...I don't even know how to describe him. He's so awful right now. Gives up so much space for underneath routes and costs the team a huge amount of yards. McCourty can't cover for him literally every single snap, he needs to step up or teams are just going to abuse him and continue to march down the field with ease.
Coleman is just as bad. We have no good CB after Butler and without a good pass rush to cover up our subpar CB play.
Speaking of the pass rush. It's putrid. A certain Jones would have helped us a lot despite all of his inconsistency issues. Sheard, Long have been invisible so far.
Our consistency in defense has to improve, it's simple as that. Hightower is the only player who has consistently played well every week. Everybody else have not been as good as they can be.
