Looking at this in one respective... Replace those names you listed with the Saints' players about 3 weeks back, and the Cowboys were shuddering a lot more! Then, the Cowboys beat those Saints. Then the Saints lost for the second time in a row on sunday. So maybe the Cowboys deflated the Saints' balloon, and had them crashing back down the earth. The Boys can do the same to the Eagles, who are not regarded as good as the Saints.
In another respective.. The Eagles own the Cowboys in big games. Sure, last season they lost to the Boys in Dallas, and then won big at home 44-6 in the last game of the season. This year, the Cowboys beat the Eagles in Philly, and now they're at home, playing on a high against an Eagles team that's won 6 in a row. The Eagles look awfully tough right now to beat.
I think the Cowboys CAN beat them, but it'll be hard, with all the momentum the Eagles are playing with. I don't think the Cowboys win sunday. I think it'll be the Eagles to win the NFC East title, which will then decide the playoff picture.
