I at least feel like they can win some games to maybe get into the hunt. Tennessee and Jacksonville are awful from top to bottom.
The good news for some of the early disappointments is this:
If you look at the AFC right now, only 6 teams have a winning record,
Buffalo
NYJ
Pitt
Houston
KC
Chargers
and the Chargers have a QB dealing with a high ankle sprain. So, for example, Jacksonville still has a chance, but it has to do with the starting QB getting back on track, and we haven't seen any signs of that (and the remaining schedule is not conducive, though I could see the Jags dropping to 0-4 this week and then making a 3 game run leading up to a very difficult 4 game stretch). Meanwhile, a team like the Ravens might have figured out that they are still a running team, and Miami might (I say might, not will) get their QB back in time to make a push. Hell, even the Bengals could, conceivably, turn things around enough to get back on track.
But, looking at the rest of the AFC, we've got 6 teams that are probably already eliminated from playoff contention:
Patriots - (problems everywhere)
Browns - (Watson sucking)
Colts - (Richardson sucking)
Titans - (problems all over the place)
Broncos - (talent issues abound)
Raiders - (problems in a lot of places, not least of all at QB)
So, at least as of now, I see an AFC with 10 teams fighting for 7 playoff spots, and the Jaguars being the least likely of the 10 to gain a berth.
