Former St. Louis Rams defensive coordinator Blake Williams — son of Gregg Williams, the former New Orleans Saints and longtime NFL defensive coordinator — accepted the same position at Southeastern Louisiana, head coach Ron Roberts announced Tuesday.

Williams’ hire is pending the approval of the University of Louisiana System Board of Supervisors. Williams replaces Karl Scott, now the safeties coach at Louisiana Tech.

“Blake is going to be a tremendous addition to our staff,” Roberts said. “He brings with him a wealth of experience as a coach at the professional level, as well as playing experience from his time at Princeton. Blake shares the same philosophy that we do, so we expect to be very similar on defense in 2015. But Blake is going to bring a fresh perspective that is going to be a plus for our program.”

Williams was brought in as the linebackers coach with the Rams in 2012 before taking over as defensive coordinator for his father.

Williams’ stay in St. Louis was the most recent of four NFL jobs in his career. Before his tenure St. Louis, he was on the Saints’ staff from 2009-11 with his dad. Williams was an offensive assistant for the Super Bowl XLIV champions, working with the offensive line.

He spent the next two seasons as linebackers coach for the Saints.

Williams got his coaching start as an intern coach for two seasons with the Washington Redskins. He was later an assistant working with the linebackers and as strength and conditioning coach for the Jacksonville Jaguars in 2008.

Williams has spent the past two seasons working as a defensive coaching consultant at William Jewell College.

A graduate of Princeton, Williams lettered four years for the Tigers. Williams played defensive back and was a special teams standout.

Williams will take over a Lions defense that led the Southland Conference in scoring and total defense a season ago, while also leading the Football Championship Subdivision in pass defense efficiency.

While Southeastern will replace several starters on defense in 2015, the cupboard is far from bare — especially in the secondary. Two-time All-America cornerback Harlan Miller leads a veteran group that features fellow All-Southland selections Micah Eugene, Denzel Thompson and Jordan Batiste.

Southeastern opened spring practice Tuesday; its spring game is 1 p.m. March 28.
