It's still unclear how the Eagles plan to use Sproles in 2014, the Philadelphia Daily News reports. Sproles' brief, likely meaningless showing in Philadelphia's preseason opener saw him run three times for 11 yards on seven plays, and he wasn't targeted in the passing game. The general expectation is that the Eagles will utilize Sproles in a somewhat opposite way during the real games, using him more as a pass-catching target than a traditional running back, but Chip Kelly is neither conventional nor transparent with his plans. No matter whether he serves as LeSean McCoy's true backup at running back or as a unique off-the-bench receiving option, the Eagles figure to make Sproles a noteworthy part of the offense one way or another. The fact that they traded for him and gave him a two-year extension implies they plan to get good mileage out of him.
