Adam Mueller, who helped the Eagles to seven wins in 2015, returned after two seasons to coach the defensive line. He is now in his second year of his second stint at MSU.

He served as an assistant defensive line coach in 2015, helping the Eagles rank among the best defenses in the conference with a 7-4 mark.

Mueller spent the 2016 and 2017 season as a graduate assistant at Boston College, following one spring season at Alderson-Broaddus (W.Va.).

Mueller finished his playing career at Connecticut in 2014, where he was the team's primary long snapper in 2011, 2012 and 2013. He helped the Husky special teams unit convert 36 field goals and 51 extra-point attempts in his career, including all 22 PATs in 2012.
 
Mueller, a native of Park Ridge, Ill., was named to the 2011 and 2012 Big East Conference All-Academic Team and to the 2013 American Athletic Conference All-Academic Team. Mueller was a semifinalist for the 2014 William V. Campbell Trophy, honoring the nation's top scholar-athlete, and nominee for the 2014 Danny Wuerffel Trophy.
 
A product of Maine Township South High School, he was the starting center for a squad that won the 2008 and 2009 8A state titles. His 2009 team finished fifth in the nation, according to the USA Today poll.
 
Mueller was a football representative on the Connecticut student-athlete advisory committee in 2014 and volunteered his time with community outreach programs Husky Reach and Goal Line. Both programs allowed student-athletes to mentor elementary-age children.
