The Facts: When the Buffalo Bills allowed productive backup running back Mike Gillislee to sign with the New England Patriots as a restricted free agent, it opened up an important job in their backfield. Williams is a logical candidate, but by no means the only one. With a new coaching staff in place led by Sean McDermott, competition is one of the most frequently heard words at One Bills Drive. "You definitely see that opening," Williams said. "But I'm trying to take it one day at a time and keep getting better."

Diehards Line: In the Bills’ rush-heavy attack, the No. 2 running back gets plenty of work. That’s not expected to change under new offensive coordinator Rick Dennison. McCoy will be 29 at the start of next season and has dealt with a few different injuries during his time in Buffalo, so it would be wise for the team to closely monitor his workload. Williams’ rookie season was quiet by statistical standards. He played in 11 games and carried 27 times for 94 yards and one touchdown. On 28 touches, he lost a pair of fumbles. Still, when the Bills chose Williams in the fifth round of the 2016 NFL Draft out of Arkansas, there was talk he could become a steal. This might be the year we start to find out if that's the case.
