Safety possibilities for Philly

There's been a considerable amount of debate over whether the Philadelphia Eagles will be running a 4-3 or 3-4 on defense in Year One of the Chip Kelly Experience. Kelly hinted that it'd be an odd-man front, and the hire of Billy Davis only increased the thought in that direction. However, as many have now pointed out, Davis has experience working with a 4-3 scheme as well, and the true nature of the Eagles' 2013 defense may well be that of a hybrid attack. But no matter what's going on up front, they need some help at the safety position.
