AFC teams I am convinced will be better than Miami in 2018:
New England
Pittsburgh
Jacksonville
That's it.
San Diego? The popular Cinderella pick since forever? They've been considerably WORSE than the Fins over the past three years. 4-12, 5-11, and 9-7 isn't putting the fear of God into me. Kansas City? With Mahomes? We'll see. Oakland? I'm not convinced Chucky is going to turn that team around in a season. Houston? Sure, DeShaun Watson is back, but does anyone remember how bad that defense was? Tennessee? Indy? Not scared. Denver? Time for Vance Joseph to show me something.
New York? Buffalo? They're rebooting at QB. Cincy? Give me one reason 2018 won't look just like 2015, 2016, 2017.... Cleveland? How about they win more than one game during this Presidential administration before we say they're playoff contenders?
The point is - there isn't a single team in the AFC without some GLARING questions, other than NE and Pitt. I still have questions about Jacksonville on offense, but that D is so good I'm not sure it matters. Miami is right in the middle of that group with glaring questions.
I don't see any reason to not say "Miami has a shot at a wildcard this year." There are about a dozen teams that can say that same thing.
