No, but you (general "you", not specific "you") would be a fool to be grading the 2016 Broncos from the same perspective as the 2016 Browns or 2016 Titans.
You're making a good point that applies to the AFC East in important ways. The perspective on the division is changing from the worst to one of the more competitive in the NFL.
The Jets and Dolphins have been viewed from the perspective of what a circus those franchises have been for the past several years. The Jets impressed me last night as a team whose head coach had them playing disciplined, prepared football, but who just don't have the manpower to compete with a team like the Patriots. The end reminded me of college games where deeper, better teams just wear down a competitor.
But the best work at this point in the season is being done by Adam Gase and the Dolphins who have a big winning streak going, good game plans, and no chaos. The perspective for how one judges Miami has completely changed. Ryan Tannehill is getting the most out of his talent and appears to be making better decisions. His QBR is higher than Russell Wilson, Andrew Luck, Eli Manning and Phillip Rivers.
The Bills are a talented football team with good players all over the place. If they could just be more disciplined. They are 4th most in penalties against accepted and 7th most in yards penalized. Classic Rex. That perspective stays the same. If the Bills stopped shooting themselves in the foot, they'd be in the playoff picture just like the Dolphins.
The Patriots are being the Patriots and positioning themselves for a first round bye and home field in the playoffs. We can quibble, but the metrics are right on track - best record in the AFC, solid defense, productive offense, excellent coaching.
In late 2016, the AFC East cannot be accused of being a bunch of "tomato cans."
