Regarding the Giants, they at least made it a game against the Cowboys and the Cowboys are playing pretty well, and there's no shame in losing to the Broncos with the way they are mauling people, but losing 38-0 to the Panthers? That is astonishing. To me that is an entire organization that isn't even trying. Being 0-3 isn't necessarily surprising but completely giving up definitely is.
Miami is a mild surprise. I doubt anyone had picked them to be 3-0. All of their wins were quality wins and two of them on the road. That is pretty darn good.
The team that stands out for me is Seattle. Of course they are good, but only giving up 27 points in three games is awesome, especially when that includes only giving up 3 points to San Fransisco.
One other stat that jumps out to me is Kansas City's +9 turnover ratio. They have 9 takeaways and haven't lost the ball once. That formula will win a lot of games.
