I think the Titans are the best team in the AFC. Bills, Ravens, Bengals, and Chargers all appear close behind, basically in a pack.
The Ravens have done pretty well at surviving a horrific plague of injuries; not sure how many of them are going to be back, or when.
I think the Raiders are pretend and will be exposed. They should get to 6-2 after their bye week, but could very easily be 8-6 or 7-7 after week 15.
Of the other teams worth talking about...
Browns may spiral, but are still talented.
Broncos are nothing worth talking about
Colts are useless - will likely get to 5-5, but only 1-3 wins the rest of the year
I don't think ANYONE wants to see the Patriots on their schedule right now. I think the Chargers game is very winnable, and if they take that one, look out: I'd expect them to have their mojo and win the following 3.
I think the 5 teams I mentioned first are close to playoff locks. Of the rest, I think the most likely to take the last 2 playoff spots are, in order, Raiders, Patriots, Browns, Colts, Broncos. I think the Patriots are the best of those teams, but the Raiders have a 2 loss cushion.
