Usually a team's RB4 wouldn't be overly relevant, however, that is not the case in Philadelphia. Now that Chip Kelly has built an all-injury team on offense, the Eagles' depth becomes very important. Kenjon Barner is projected to be Philly's RB4, which is no surprise being that he's a former Oregon Duck. With the backs he has in front of him, there is a great chance he sees touches this season and fits perfectly in Kelly's offense. The RB1, DeMarco Murray , has played 16 games only once in his four NFL seasons and endured just under 500 touches last season.
