Air Force defensive coordinator Tim DeRuyter is keeping mum on speculation about his future.

DeRuyter, who just completed his third season as the Falcons’ defensive boss, has been mentioned as a candidate for several defensive coordinator openings, including posts at Georgia and Texas A&M. The Austin American-Statesman reported this week that the Aggies are interested in DeRuyter.

But DeRuyter declined to discuss the speculation Friday through academy sports information director Troy Garnhart. DeRuyter was in California this week recruiting.

A 1985 academy graduate, DeRuyter has become a hot name nationally by revitalizing a porous Falcons defense. Upon his arrival with head coach Troy Calhoun in 2007, DeRuyter scrapped a bend-but-don’t-break scheme and replaced it with an aggressive, 3-4 set.

DeRuyter’s defensive unit was among the nation’s best in 2009. The Falcons finished the season ranked 10th in scoring defense and 11th in total defense. And the unit’s performance in the Armed Forces Bowl against Houston was a masterpiece. The Falcons limited the nation’s top-ranked passing offense to a season-low 222 yards through the air and picked off quarterback Case Keenum six times.

DeRuyter was the Falcons’ highest-paid assistant in 2009, earning $205,000. But he likely would be offered a bigger salary at school from an automatic-qualifying BCS conference.
