Things are really starting to shake out in the 2012 NFL season.
Through the first few weeks, sure, it was difficult to tell what truly constituted an upset. Was it just the Vegas odds? Which teams were truly "better"? Which teams were just living off hype? How much did the replacement refs screw with the natural balance of NFL order?
Now, just over halfway through the season, it's easier to distinguish the NFL's haves from the have-nots. The problem is, in an era of parity, even the haves have big fatal flaws. No one is bulletproof—no one.
So which teams have the best chance of being upset this week?
