This place is rocking. Arrington provided the Cardinals' most recent kick-return touchdown before this one, against the Vikings in 2006. Great way to start for Arizona. No question, too, that the Arizona fans have filled in enough seats to make this look more like a 90-10 split on a fan-loyalty percentage basis.
Update: The Cowboys' fans presence became more obvious when Dallas gave tem something to cheer about. I would now say Cowboys fans could comprise 15 to 25 percent of all fans here.
