As for the Cardinals celebrating...
It didn't offend me, I guess, that they whooped it up like they'd just beat the Pats for a SB win instead of a Week 2 win...
I just figured, "Hey, they have to celebrate something this year, I guess." ;)
(Sorry, I don't see the Cardinals coming back...the Seahawks and Rams look like they're making strides, and we might have a fun division in a year or two in the NFC West, but as for the Cards...nah, that window of opportunity has come along and already shut--when they lost Warner to retirement, they lost the best chance they had at being a championship team, and with the 49ers rise back into the NFL Elite and the Seahawks surging forwards and seemingly having found a good rookie QB in Russell Wilson...and the Rams showing some offensive promise today...sorry, not in the cards for the Cards.)
