to rise out of his stance. The jarring and unexpected hit knocked the ball loose and into the hands of linebacker Teddy Lehman, who stepped into the endzone for a touchdown and sealed the game for Oklahoma. This play has been immortalized on a mural plaque at the Roy Williams Strength and Speed Complex at the University of Oklahoma. The complex is named for Williams both for his athletic achievements and for his donation of approximately $100,000 towards its construction. Professional career Dallas Cowboys Williams was selected by the Dallas Cowboys with the eighth overall pick of the 2002 NFL Draft after a trade with the Kansas City Chiefs. He was known throughout the league for his hard hitting and his tackling skills during running plays. With the arrival of Ken Hamlin from Seattle, Williams had the luxury to move closer to the line of scrimmage to blitz and cover short passes during nickel or dime situations. As a rookie in 2002, he was moved to free safety in order to play alongside strong safety Darren Woodson. However, the Cowboys defensive scheme that year allowed both players to interchange positions so as to confuse opposing offenses. He tied the franchise single-season record for most interceptions returned for touchdowns with two. Williams was also the runner-up for Defensive Rookie of the Year. In 2003, Williams with the mentoring of Woodson, enjoyed a stellar season and his first trip to the Pro Bowl as he was part of the Cowboys' number one ranked defense and helped lead the team to its first playoff game since 1999. In 2004, Woodson suffered a herniated disc in training camp and was forced to sit on the sidelines. Williams' struggles were more apparent as he was forced to play more coverage due to the inexperience and inconsistency of the Dallas cornerback position. After the season, the horse-collar tackle was banned. This action is now referred to as the "Roy Williams Rule", as the rule was introduced the 2004 season, during which Williams used the technique on plays that resulted in three significant injuries. Williams is occasionally referred to by fans as "Biscuit", in reference to a statement in a 2003 press conference by former head coach Bill Parcells who, noting Williams' weight, said that he was "a biscuit short of a linebacker".
