Brett Diersen, a defensive line coach with extensive Midwest ties, enters his third season as defensive line coach while also serving as the recruiting coordinator for the Northern Illinois University football program in 2015.

In his first two seasons at NIU, Diersen has coached four All-MAC selections: Ken Bishop and Joe Windsor in 2013 and Jason Meehan and Perez Ford last season. His defensive linemen have made a habit of getting after opposing quarterbacks, helping the Huskies tally 66 sacks for a loss of 430 yards under his direction.

The Huskies defensive line played a big role in NIU’s Mid-American Conference title in 2014 as the NIU amassed 32 sacks, forced 24 fumbles and held opposing rushers to 4.2 yards per carry last season.

Entering the 2013 season Diersen was tasked with rebuilding a defensive line that lost three of four starters from the 2012 MAC Championship team. Fortunately, a key player from that 2012 defensive line, noseguard Ken Bishop, returned for his senior season. Under Diersen’s tutalge, Bishop made 70 tackles, including seven tackles for loss, and two interceptions, on the way to becoming a seventh-round draft pick by the Dallas Cowboys in the 2014 NFL Draft.

Diersen spent the 2012 season at Florida Atlantic University where he coached the Owls’ defensive line and served as special teams coordinator. In 2011, he was the defensive ends coach and recruiting coordinator at Indiana after spending the 2008-10 seasons on the University of Nebraska coaching staff, where he assisted in working with special teams and a defensive line that featured Ndamukong Suh, who was named the Associated Press National Player of the Year and won the Bronko Nagurski, Rotary Lombardi, Outland and Chuck Bednarik awards.

 The connec­tion between Carey and Diersen dates back to 2000 when Carey took over as offensive coordinator and offensive line coach at Wisconsin-Stout, where Diersen was a graduate assistant on a Blue Devils team that went into the Division III playoffs undefeated. After coaching the defensive line, outside linebackers and special teams at the University of Dubuque from 2001-03, Diersen returned to UW-Stout as defensive coordinator in 2004. The two remained with the Blue Devils through 2006.

A native of Appleton, Wis., Diersen spent the 2007 campaign as defensive line coach at Minnesota State-Mankato before going to Nebraska the next season.

As a player, Diersen was a three-time all-conference defensive end at Huron (S.D.) University from 1994-98, where he earned his bachelor’s degree in 1998. He added a master’s degree in education from UW-Stout in 2005.

Diersen and his wife, Jenna, have two sons, Brody and Hudson.
