Mississippi State didn’t waste any time searching for a new defensive coordinator after its Orange Bowl loss to Georgia Tech on New Year’s Eve. Less than a week later, the Bulldogs reportedly have their man.

Former Mississippi State defensive coordinator Manny Diaz will return to Starkville to regain control of the Bulldogs defense beginning in 2015, according to Sports Illustrated’s Pete Thamel.

Diaz will fill a vacancy on Dan Mullen’s coaching staff created when former Mississippi State defensive coordinator Geoff Collins took the same job on Jim McElwain’s staff at Florida.

The terms of Diaz’s new deal with MSU have not been announced as of early Monday afternoon.

Diaz served as Mississippi State’s defensive coordinator and linebackers coach for one season in 2010, leading MSU to the nation’s No. 22-ranked scoring defense and the SEC’s No. 3 scoring defense. He left the Bulldogs after one season and spent three as the defensive coordinator at the University of Texas before the school parted ways with Mack Brown and his staff following the 2013 season.

He spent the 2014 season as the DC at Louisiana Tech, which boasted the No. 2 scoring defense in Conference USA in his lone season with the Bulldogs.

Diaz will take over a Mississippi State defense that ranked eighth in the SEC in scoring defense and allowed more completions of 30 or more yards than any other school in the conference. The Bulldogs ranked sixth in the conference against the run and allowed Georgia Tech to rush for more than 400 yards in its Orange Bowl victory over MSU.
