Williams got back to his wild ways on Saturday with No. 21 USC hosting Arizona State.
The freshman defensive tackle made six tackles, the most of any player on the defensive line, sacked ASU quarterback Taylor Kelly and even grabbed the first interception of his young USC career.
"The ball came right to me," he said of the pick, "then everything went in slow motion."
Williams says after the poor showing from the Trojans' defense the last two weeks the unit decided to change their mindset and refused to let "that" happen to them again.
The defense held ASU to just 250 yards.
