With their sixth-round pick in the NFL Draft, the Steelers picked Nebraska guard Keith Williams to help bolster their offensive line. Williams had a pre-draft visit with the Steelers, and Pittsburgh continues to need help with its offensive line (having picked only Marcus Gilbert so far), so this pick is no surprise.
Here’s a good video profile of Williams. He has good size (6-foot-4, 318 pounds) and some potential, but he apparently needs to be more consistent, and he also apparently "lacks mental toughness." That doesn’t sound like a typical Steelers player, so the Steelers must have liked what they heard from him in the pre-draft visit.
By my count, this is the fourth player the Steelers have drafted who came in for a pre-draft visit (Gilbert, Curtis Brown, Cortez Allen, and Williams). It could be that their seventh-rounder will be another visitor, such as Marshall lineman Mario Harvey or South Carolina offensive lineman Jarriel King.
In addition, the Bears took OLB J.T. Thomas from West Virginia the pick before.
