There are still six teams without a loss yet after five weeks. They range from known juggernauts like the New England Patriots and Green Bay Packers, to the Denver Broncos, a team in transition.

Usually the Seattle Seahawks are among that group, but a once-punishing defense somehow allowed 17 fourth-quarter points during a loss to the Cincinnati Bengals. Now the two-time defending NFC champs are floating in the middle at 2-3 and far removed from those pristine, undefeated records.

At first that seems totally wrong, because the Seahawks couldn't possibly have the same record as the Cleveland Browns and Oakland Raiders. But it's real, just like the suddenly perfect Atlanta Falcons after they won only six games in 2014.

Let's try to make sense of it all with power rankings. Remember, these rankings aren't the standings. Instead, what follows is an analysis of how each team stacks up based on performance, regardless of what its record says. It's subjective, sure, but agreeing on everything (or anything) isn't fun, right?

And remember, I probably hate your favorite team.
