Derek Mason isn't going to do it all himself.

Vanderbilt's football coach is going to take on more of the workload in his second season, though.

Mason announced Monday that he would do double duty this fall as head coach and defensive coordinator. He came to Vanderbilt from Stanford, where he was a successful defensive coordinator.

Mason also formally named Andy Ludwig offensive coordinator and quarterbacks coach. Ludwig spent the last two seasons as offensive coordinator/quarterbacks coach at Wisconsin.

"After weeks of deliberation and conversations with many coaches, I've decided to call our defense," Mason said in a release. "No one knows our defense and what we can accomplish with this defense more than I," Mason said. "At the same time, I expect to attract one of the nation's top coaches to guide our cornerbacks."

After going 3-9 in his first season, he fired four staff members, including both coordinators.

Ludwig replaces Karl Dorrell and will help hire a new wide receivers coach. Mason will use the opening created by the departure of former defensive coordinator David Kotulski to hire a cornerbacks coach. Last year's secondary coach, Brett Maxie, will focus on the safeties.

"I am excited to welcome Andy Ludwig to Nashville and Vanderbilt University. We have attracted one of the brightest offensive minds and most successful coordinators in college football to the Commodore program," Mason said. "Our student-athletes are gaining a tremendous mentor in Andy Ludwig, a man of integrity who demands excellence on and off the field."

Wisconsin was 20-7 during the last two seasons and had two of the most prolific offenses in program history.

Ludwig also has been offensive coordinator at San Diego State (2011-12), Cal (2009-10), Utah (2005-08), Oregon (2002-04) and Fresno State (1998-2001).
