This one doesn't need a ton of explanation; he's Darren Sproles, and Chip Kelly is Chip Kelly.

Don't expect a 45-yard touchdown again, and he's untouchable in non-PPR formats. But under Kelly, Sproles looks more useful than he's been in years. Pick up for the boom potential, perfect for matchups where you're the underdog and you need some big-play potential to go along with all of those prayers.
