Fred Jackson, C.J. Spiller and Ronnie Wingo are back. They added free agent Anthony Allen in January and free agent Anthony Dixon in March.

Today, the Bills traded future draft considerations to the Philadelphia Eagles for running back Bryce Brown.

Eagles star LeSean McCoy wished his backfield mate farewell with a Twitter comment that didn't sit well with Jackson.
