DeRuyter was fired from his post as Bulldogs head coach on Oct. 23, 2016, and was replaced by former Cal head coach Jeff Tedford after Fresno State went 1-11.
DeRuyter was one of the first names brought up by sources as a candidate for the position back in December, before now-former head coach Sonny Dykes was dismissed. He has interviewed for the same job -- the one he now has -- twice, with two different potential bosses -- first with Dykes, and most recently with new head coach Justin Wilcox.
Most prescient is the fact that DeRuyter has a history of converting 4-3 defenses -- the base defense which the Bears ran under Art Kaufman -- into 3-4 alignments, something that Wilcox has already said he will be doing.

The man DeRuyter replaces, Kaufman, was the fifth-highest paid assistant coach in the Pac-12 in 2016, at $593,000 per season. His contract -- originally expiring on April 30, 2016 -- was extended to run through April 30, 2018. On Dec. 15, it was announced that Kaufman would not return, though it is unknown whether he and Cal exercised the mutual termination clause, allowing both parties to walk away without any financial consequences, or whether he was fired. Terms for DeRuyter's deal have yet to be announced.
Kaufman's biggest weakness was his recruiting -- his former boss at Cincinnati, Tommy Tuberville, told the Cincinnati Inquirer on Jan. 4, 2014, that his firing of Kaufman was "more about recruiting," and during his time in Berkeley, Kaufman -- who specialized in coaching linebackers -- had landed four linebacker commits.
DeRuyter, 54, is an alumnus of Bellflower (Calif.) St. John Bosco, a fertile recruiting pipeline that's produced multiple Power 5 players, including Bryce Treggs, Josh Rosen, Wyatt Davis, Keith Price, Damien Mama, Sean McGrew, Jaleel Wadood, Naijiel Hale and D.J. Morgan, with one of the top 2018 defensive backs in Jaiden Woodbey.

After the 2015 season, the Bears learned that they would be losing two linebackers -- Hardy Nickerson and Michael Barton -- to graduate transfer, one to injury retirement (Jake Kearney) and one elected not to pursue a sixth year (Nathan Broussard). Kaufman brought in one high school signee -- Cameron Goode -- and one JuCo signee, in Jordan Kunaszyk, while converting a safety (Derron Brown) to an outside linebacker. Goode redshirted, and Brown was sidelined with a broken hand.
Currently, the Bears have seven linebackers on scholarship, and are bringing in one linebacker in the 2017 class in state champ Paul Scott, although there's the potential to move several Cal defensive linemen back into the outside linebacker spot, including JuCo signee Alex Funches, and defensive ends Cameron Saffle and Evan Weaver.
Before his tenure in the San Joaquin Valley, DeRuyter had a history of rebuilding defenses, turning Ohio from the 99th-ranked defense, nationally, into the 22nd-ranked unit in the nation by the time he left for Nevada. In Reno, he turned the Wolfpack from a 78th-ranked defensive unit into the 48th in the nation, in his second season.
From there, DeRuyter moved to Air Force from 2007-09, as defensive coordinator and safeties coach, bringing a 3-4 defensive scheme with him. Before his arrival, the Falcons were 78th in the nation in scoring defense and total defense, and by the time he left, they ranked 10th and 11th, respectively.

Under his tutelage, Super Bowl 50 MVP Von Miller became the 2010 Butkus Award winner while at A&M.
In his first year at Fresno, DeRuyter's team limited opposing teams to 23.8 points per game (37th in the nation) in a 9-4 campaign. In 2013, the Bulldogs allowed 28.1 points per game (74th), 32.4 in 2014 (101st), 38.1 in 2015 (119th), and in eight games in 2016, DeRuyter's Fresno State team allowed 34.1 points per game before he was relieved of duty.
During his tenure in Fresno, DeRuyter went 30-30, reaching three bowl games, but his offenses declined over the course of his tenure, averaging 20.5 points per game in his final eight games, after averaging 37.92 in 2012, 43.38 in 2013, 24.57 in 2014 and 22.25 in 2015.
Under Kaufman this season, Cal was 127th in the nation in rushing yards per game (272.9) and 128th in rushing yards per carry (6.16). The Bears were 127th in scoring defense (42.6 points per game), 82nd in passing yards allowed per game (245.4), 107th in passing efficiency defense (145.84), 105th in team sacks (18) and 125th in total defense, giving up 518.3 yards per game. Cal's 67 offensive touchdowns allowed were the most in the nation.
For comparison's sake, the Bears' 2013 defense -- widely considered the worst defense in the history of college football, and a defense which cost Buh his job -- allowed 188.6 yards rushing on defense per game (88th in the nation), ranked 118th in defensive passer efficiency (165.44), 122nd in scoring defense (45.9 ppg), 122nd in total defense (529.6 yards per game) and 123rd in passing yards allowed (341). That team gave up 72 offensive touchdowns -- 122nd out of 123 FBS teams.
