Williams only played one year of high school football. In his lone season, his senior year, Williams played both offensive and defensive line. He recorded 25 tackles, two interceptions (one of which he returned for a touchdown), one fumble recovery, and knocked down two passes. Due to only playing one season, he was lightly recruited. Williams chose Samford for its close proximity to his home.
Williams redshirted his first season. In 2009, he played in seven games and had three tackles. The following year, he played in 11 games, and recorded nine tackles and a forced fumble. In 2011, he became a full-time starter, and played in every game. He had 23 tackles (three for loss), and two sacks. Williams had his best year in his redshirt senior season. He tallied 31 tackles (eight for loss), and six sacks. He was All-Southern Conference second-team in 2011, and first-team in 2012
