Easy as 1-2, 3 (and 0)
Giants and Cowboys have stumbled down the stretch recently.
The Eagles' chances of winning the NFC East are predicated on them winning their last three games and both the Giants and Cowboys going 1-2 (or worse).
It turns out that since 2001, the Giants and Cowboys have finished the same season 1-2 in their last three games five times (2001, '04, '06, '07, 08).
The other part of the equation (Eagles going 3-0) might turn out to be the harder one to meet, since they have finished with three wins only twice (2006, '07) in 10 seasons. And two of their last three games are at home, where they have won just once in their last nine games (including playoffs).
