Williams was just outside of Rivals’ top 100 in 2016 as a four-star recruit coming out of Birmingham. He committed early to Auburn, which was his favorite team growing up, initially before reneging and flipping to the Crimson Tide just before his senior season after attending a camp there. Williams redshirted as a freshman. In 2017, Williams joined Bama’s DL rotation — mostly as an end in their 3-4 front — and totaled 20 tackles (6.5 for loss) and two sacks in 14 games as a reserve for the national champions on a deep, talented defensive line. But in 2018, Williams broke out in a big way in his redshirt sophomore season, earning AP first-team All-America and first-team All-SEC notice and being named a finalist for the Bronko Nagurski Award, the Bednarik Award and the Outland Trophy. He started 15 games at nose tackle and collected 71 tackles (19.5 for loss), eight sacks, one pass defended and a safety.
