Since 2007, Sproles has the most all-purpose yards of any player in the NFL. All the other players in the top five have been to at least two Pro Bowls. The problem for Sproles when it comes time to vote for the Pro Bowl is that he's difficult to classify. He is a running back who has averaged only 3.6 carries per game during his career. He's a receiver who averages only 9 yards per catch. He's a returner who has focused almost entirely on punts in recent seasons. When Sproles is compared to other players at those positions, his numbers often pale.
