'Despite boasting a full convoy of backs, the Bills took Arkansas running back Jonathan Williams, who missed all of the 2015 season after undergoing surgery to repair a torn ligament in his foot. Splitting carries the year before, he rushed for 1,190 yards and 12 touchdowns. He'll now join a backfield that includes LeSean McCoy, Karlos Williams, Mike Gillislee and James Wilder Jr. Last year, this group was hit hard by injuries at various points. In a 14-13 win at Tennessee, Buffalo was forced to start Boobie Dixon (19 yards on seven carries) and Boom Herron, picked up off the streets, even had a team-high nine carries that game.'
