The Facts: The departure of Mike Gillislee likely means an increased role for Williams as the Bills attempt to replace the former's 2016 production (577 yards and eight touchdowns on 101 carries).

Diehards Line: Williams was active for 11 games as a rookie last season, rushing 27 times for 94 yards and one touchdown. A 5-11, 223-pound product of Arkansas, Williams could provide a short-yardage replacement for LeSean McCoy. The question is whether Williams, with a heavier load of carries, can rival Gillislee's efficiency last season -- a league-best 5.7 yards per carry. But before potential fantasy owners bump up Williams' potential draft value this fall, ESPN.com's Mike Rodak reminded us to consider the possibility that fullback Mike Tolbert could poach some short-yardage and goal-line carries. When signing Tolbert last month, the Bills emphasized Tolbert would be used as more than just a lead-blocking fullback, indicating that Tolbert could take some carries away from the more traditional running backs on Buffalo's depth chart.
