Running Back. Stanford. Christian McCaffrey. 14. player. 54. With running backs Ryan Mathews and Darren Sproles aging, the Philadelphia Eagles could be in a market for a tailback in this year’s NFL Draft. There’s no better way to help out a young quarterback than a solid running game. They can add an all-purpose, dual-threat running back in Christian McCaffrey. He’d be a solid back in Philadelphia for years to come.
