[1] Because Chris Simms was left-handed, Williams was projected as a top prospect for left tackle, widely considered the most important position on the offensive line.
He was considered one of the two top prospects in the 2002 NFL draft, alongside Bryant McKinnie, a natural left tackle from the University of Miami.
After a failed attempt to convert Williams to guard, and spending some spot duty at defensive tackle in goal-line situation, he was released in the 2006 offseason.
Williams was rewarded for his efforts on March 6, 2010, with a new two-year contract after new head coach Mike Shanahan and his staff reviewed game film of him.
