Williams, a 5-foot-11, 230-pound bruiser, is thought to be a third-round pick by some, but could jump ahead to the second if there is a run on running backs.
The Steelers helped ignite that trend last year when they selected Michigan State RB Le'Veon Bell in the second round. Cincinnati had selected Giovani Bernard, and after the Steelers took Bell, Denver took Montee Ball and Green Bay took Eddie Lacy.
Lacy was the 2013 NFL Offensive Rookie of the Year, and Bell broke the Steelers' rookie record for total yards from scrimmage.
Pittsburgh signed LeGarrette Blount this offseason as well, and he and Bell make up the only running backs with NFL experience on their roster. It seems likely the Steelers will address the running back position in this draft at some point.
