The move ends Williams’ return to college football after just one month. New Gators coach Jim McElwain hired Williams early last month.
The 40-year-old Williams had spent the last three seasons coaching the defensive line for the Raiders. He replaces former Dolphins defensive line coach Kacy Rodgers, who left last month to become defensive coordinator for the New York Jets.
Williams coached the defensive line at Texas A&M from 2010-11 and the position at Purdue prior to that for four seasons. He was also defensive line at coach at Akron (2004-05), Youngstown State (2002-03), North Carolina A&T (1999-01) and Fort Scott Community College (1998).
The Los Angeles native played nose tackle at East Carolina from 1995-96. The Dolphins had an 8-8 record this past season under coach Joe Philbin, who has a 23-25 mark in three seasons.
McElwain was hired in December from Colorado State, where he had a 22-16 record in three years, including a 10-2 mark this past season. He replaced Will Muschamp, who had a 28-21 record in four seasons with the Gators.
