Week 4 in the NFL brings us a little clarity and a little separation. There are still a handful of unbeatens and still a few winless teams as well. As usual, there is a lot in the middle and while most of the middle hasn’t distinguished itself one way or the other, we want to know which teams at the top and bottom are giving us a true vision of what they are capable of this season. We try to do all we can to separate the wheat from the chaff.
