After a relatively slow first two days of free agency, the Eagles made a splash Thursday morning when they acquired running back/returner Darren Sproles from the Saints in a trade, according to an NFL source. The exact compensation for Sproles was not immediately known. The Eagles are expected to announce the move Tuesday afternoon. There was reportedly multiple teams interested in trading for the 30-year-old Sproles. Some thought he would eventually be released. But the Eagles pulled off a bit of shocker and got another piece for Chip Kelly's fast-paced offense.
