Philly has stumbled out of the gate to a 2-4 start, but they are still one of the most talented teams in the NFL. However, another loss would all but eliminate any chance of them winning the NFC East.
The Cowboys have also gotten off to an up-and-down start to the year, but they come into the game with a 3-3 record and sit just one game back of the first place New York Giants.
A win for the Cowboys on Sunday could be a springboard to a nice division lead if they beat the teams they are supposed to beat.
They'd effectively be three games up on the Eagles with a two game lead in the loss column and a win in the head-to-head matchup. They'd be 2-0 in the division and have a much easier strength of schedule ahead than their chief competition the rest of the way.
The Cowboys have a soft stretch of schedule—they play Seattle, Washington, Miami and Arizona in a five-week span—coming up after this one. Building on Sunday's dismantling of the lowly St. Louis Rams, another win would enable Dallas to head into that stretch with some momentum and confidence.
Conversely, after an easy matchup with Miami this week, the Giants head into their toughest stretch as they end the season with games at New England, at San Francisco, vs. Philadelphia, at New Orleans, vs. Green Bay, at Dallas, vs. Washington and at the New York Jets.
To say this game is the turning point of the season comes close to being an understatement. All Cowboys-Eagles games are huge events, but this one feels even bigger.
The Cowboys know exactly what it's like to have a season crumble amidst outsized expectations—they experienced it last year—and now have a chance to make the Eagles feel their pain.
