Here's a write-up on DeRuyter as one of the names in the Ole Miss DC search:
Tim DeRuyter
Former head coach at Fresno State
DeRuyter’s time as a head coach in Fresno was inconsistent—he won two Mountain West titles but went a combined 30-30 overall. His track record as a defensive coordinator, however, is impressive. Before taking over Fresno State in 2012, he was the defensive coordinator at Ohio, Nevada, Air Force and Texas A&M, showing the ability to turn a defense around quickly at all of those stops.
When DeRuyter took over at Ohio in 2002, he jumped them from 99th in total defense to 22nd. He then moved to Nevada, where he orchestrated a jump from 78th in total defense to 48th in just two years. He then took Air Force from 78th to 10th in scoring defense and from 78th to 11th in total defense. In 2010, he jumped A&M from 104th in scoring defense to 21st in one year.
