I'd definitely throw my money down on Philly winning the NFC Least. Dallas will have a catastrophic choke at the end of the season. It's pretty much the most predictable thing ever.
In fact, the Cowboys host Philly in the final game of the season. I'm predicting an epic choke in front of the hometown fans that gives Philly the division. Of course, that's akin to predicting that the sun will rise tomorrow.
