It's too soon to suggest that Murray signing with the 
    Eagles alters the balance of power in the NFC East, but the move definitely diffuses the potency of the 
    Dallas Cowboys' offense. Murray set the table for the unit one season ago as the premier workhorse runner in football; his success altered how opponents defended 
    Tony Romo and Co. Instead of playing coverage-first schemes, defensive coordinators used more eight-man fronts to slow down the run. This opened up the field for 
    Dez Bryant, 
    Terrance Williams and 
    Jason Witten on play-action throws. In addition, the steady production from Murray protected the 
    Cowboys' defense because the team could rely on a ball-control approach to play keep away from their opponents. With fewer overall possessions, the 
    Cowboys' defense was able to compete and win battles against the heavyweights in the NFC. With Murray no longer in the fold, the 
    Cowboys could be exposed as an average squad in 2015. 
 
  For the 
    Eagles, the signing gives Chip Kelly another talented runner in the stable. He can creatively adjust his lineups to take advantage of favorable matchups on the ground or in the passing game. With an efficient pocket passer in the fold to complement a dynamic running game -- also bolstered by the addition of 
    Ryan Mathews -- the 
    Eagles' offense can rely on an RB-centric attack to make a run at the NFC East crown. 
   
     I would say that right now, the 
    Philadelphia Eagles would be the favorites in the NFC East, what with all the moves they've made. I would think they'll have the capability to play pretty good offense. But you've got to remember one thing: This is a game of chess, and the 
    Dallas Cowboys are surely working on a countermove, whether that means acquiring someone who's already in the league or looking to the draft. The offseason isn't over, and the 
    Cowboys will not stop trying to get better. They might land someone who more than makes up for the loss of 
    DeMarco Murray -- say, someone like 
    Adrian Peterson. Jerry Jones is in second place, so to speak, right now, but do not count Jerry Jones out. Knowing his penchant for big moves -- and trading for Peterson would obviously be a big move -- I would expect 
    something to happen still. 
   
     With the exception of the 
    Sam Bradford trade, Chip Kelly has been masterful to kick off the new league year. By snagging 
    DeMarco Murray away from the 
    Cowboys, Kelly simultaneously struck a huge blow to a division rival -- Murray brought balance to Dallas' offensive attack in 2014, helping 
    Tony Romo achieve the best season of his career -- and found a playmaker who fits his style more than the recently departed 
    LeSean McCoy. Murray will pair nicely with newly signed 
    Ryan Mathews, giving the 
    Eagles a potent 1-2 punch that should make the rest of the NFC East shiver. 
 
  Although many people were shocked when Kelly shipped McCoy off to the 
    Bills for 
    Kiko Alonso, the 
    Eagles have since more than addressed the vacancy -- and now they also have one of the best young linebackers in the game! 
   
     I'm not sure 
    DeMarco Murray affects much in the NFC East. After all, no one expected Dallas to do anything 
    last year, so in order to say this move affected the "balance of power," we are almost assuming the 
    Cowboys are the favorite to repeat. Moreover, Philadelphia just got rid of a running back who, frankly, has been more durable than Murray. Are we really ready to say Murray is a better player than 
    McCoy? Remember who led the NFL in rushing in 2013? It wasn't Murray. It was Shady. This draft is quite deep at running back. 
    Joseph Randle has shown potential (though he has had 
    off-the-field issues). The other backup in Dallas, 
    Lance Dunbar, is an explosive change-of-pace running back. So while the departure of the leading rusher from last season isn't wonderful for the 
    Cowboys, it doesn't mean Dallas can't win. It also doesn't necessarily translate to the 
    Eagles being better.
