According to the Arizona Republic, head coach Bruce Arians raised some eyebrows early in training camp when he said outside of David Johnson, there was no set pecking order among the rest of his running backs and that there were four players up for the final three spots at the position. One of them is Williams, a fourth-year pro out of Utah State. “Kerwynn’s one of those guys that if you give him his opportunity, he does great with it every time,” Arians said. “You’re kind of stupid if you don’t give him one because every time, he does it.” In the team's Aug. 12 exhibition game against the Raiders, Williams worked ahead of Andre Ellington at halfback in addition to getting the first shot to be the team’s top punt and kickoff returner since rookie T.J. Logan was placed on injured reserve with a dislocated wrist. And when the Cardinals released their latest depth chart (Aug. 15), Chris Johnson and Williams are listed co-backups at running back behind David Johnson.
In terms of offensive role, there are going to be limited opportunities behind David Johnson if all goes according to plan. And by limited, I mean essentially scraps.
2017 Bottom Line
Williams' most notable fantasy impact could lie in the possibility he knocks Ellington off the roster. Short of that (and it's certainly not chiseled in stone), Williams will be a non-factor fantasy wise, barring injuries to either of the Johnsons.
