Buffalo Bills RB Jonathan Williams has worked on improving his ball security this offseason after head coach Sean McDermott said it was an area Williams needed to work on. Williams lost two fumbles on 28 carries in 2016.

Footballguys View: Williams has good dynasty potential because of his natural running style, instincts for the position and power between the tackles. He needs to hang onto the rock if he wants to get some touches as LeSean McCoy’s primary backup in 2017.
