How Williams' Absence Affects Bills' Backfield

Williams is a vital piece of the puzzle in Buffalo, despite LeSean McCoy's return from a hamstring injury.

The former Florida State standout had only 40 yards rushing on 18 carries in Week 4, but he did find the end zone for the fourth consecutive game.

Williams is averaging 5.4 yards per tote and was the Bills' most effective running back when McCoy struggled through an injury.

The FSU product was Buffalo's fifth-round pick this year, and he has given Rex Ryan another great weapon in the running game, which prompted the team to release veteran Fred Jackson during the preseason. The Bills have also featured Boobie Dixon and Boom Herron this season but saw less success with them carrying the rock compared to Williams and McCoy.

Williams has been a great complement to McCoy, thanks to his 230-pound frame and pure power, and even though his first career start wasn't ideal, he has all the makings of a back who is capable of carrying the load.
