The Facts: Sproles' role in Chip Kelly's offense will be one of the intriguing plot lines as we encroach upon training camp. In an interview this week with NFL Media's Rich Eisen, teammate LeSean McCoy crowed about playing with the diminutive back. "Sproles has the quickest feet I've ever seen out of any player," McCoy said. "He'll help us out tremendously. I think the best thing about him, what he brings to this team is not only leadership and experience, but also just another big playmaker on the team. You talk about losing DeSean (Jackson), but I think Howie (Roseman) and Chip did a great job of bringing another playmaker to our team."

Diehards Line: Sproles is expected to play roles in the running game, special teams and passing game -- just don't make the mistake of calling him a receiver. As NFL.com suggests, the slippery duo of McCoy and Sproles dancing in the Eagles' backfield will stress opponents with their versatility. "With me and him in the backfield together it will definitely cause an issue with the defense," McCoy said. ... The question is how much work Sproles will get? We'll start to gain a better understanding of that when the Eagles open camp on July 25.
