News: Ex-Cowboys running back Felix Jones has signed with the Eagles. The back agreed to a one-year deal according to multiple reports. He's expected to add depth to an already fairly stocked running back corps that includes starter LeSean McCoy and backups Bryce Brown and Chris Polk.
Analysis: Brown specifically was a sleeper before the news and still is someone to consider drafting late this summer, but the arrival of Jones means serious competition for these backs. Jones' versatility and decent speed will make him a threat to contribute behind McCoy. Whoever is the second-string back in Philadelphia could be good for as many as 10 touches per game and a candidate to step into a major role if something were to happen to McCoy. Brown has late-round appeal while Polk does not.
News: Running back Chris Polk of Washington agreed to sign with the Eagles as a rookie free agent following the NFL Draft. Polk skipped his senior year to enter the draft but wasn't selected. He averaged 101.2 rushing yards a game for his career at Washington and he's second on the school's career yardage list (4,049 yards) to Napolean Kaufman. Polk was red flagged by teams in the draft because of a supposed degenerative shoulder problem. When Polk began hearing that teams were concerned about his shoulder, he had it checked by well-known orthopedic surgeon Dr. James Andrews. According to team sources, Andrews wrote a letter stating that Polk had some scarring from the surgery, but there was nothing that should prevent him from being drafted or playing football. "I know teams are concerned about my shoulder, but I also heard somebody say something about a degenerative hip and there is just no truth to that," Polk said according to The Sports Xchange. "I had labrum surgery on the shoulder a year ago and it didn't slow me down last season."
Analysis: Polk's college production and skills certainly suggested that he get picked in the draft, but obviously some NFL teams got scared off by the injury. With the Eagles he can battle for a roster spot at little to no risk. He's worth a late pick in dynasty/keeper leagues and in rookie-only drafts.
