It's artificial.
What I mean is, to some degree, these records are a product of schedule anomalies that will soon be remedied.
Many of these 7-2, 6-3 teams are either in the same divisions or haven't had their AFC crossovers yet. Yes, they won the games they won, but they also still play each other, sometimes twice between now and the end of the season.
In other words, there will be many losses allocated between these teams in the coming weeks, because they all play each other. It's just math.
Some could very well still rise above, but I predict a lot of split division series and up and down weeks for these teams to come.
This is exactly the dream scenario that the league wished for when they started backloading division games. When you have something like the AFC West, AFC South and even the AFC North where multiple teams have a real shot and they all play each other still, it makes for weeks of compelling games later in the year and teams not resting guys.
Good news: the Eagles game and red helmet games will almost certainly matter for the Bills (and Eagles).
