Shannon Morrison returned to his alma-mater to serve as linebackers coach in May 2005 and took over as Marshall's safeties coach in 2007.
The former MU standout tutored junior safety C.J. Spillman in 2007 as he recorded a team-high 131 tackles en route to earning second-team All-Conference USA honors.
Morrison oversaw a Thundering Herd linebacking corps in 2005 that featured two of Conference USA's top tacklers in juniors Dennis Thornton (104) and Matt Couch (97). The linebacker unit also helped the MU defense limit opponents to a C-USA best 340.27 yards per game. During the 2006 season, Morrison coached linebacker Matt Couch to second-team all-conference honors and linebacker Josh Johnson to honorable mention accolades.
Morrison was a four-time letterwinner at Marshall and was an All-Southern Conference and honorable mention All-America selection for the Herd in 1994. During his Marshall career he intercepted 11 passes and is still sixth on the Thundering Herd's all-time interceptions list. He also helped Marshall to its first-ever national title in 1992 and was coached by Mark Gale, the Thundering Herd's Assistant Athletic Director for Football Operations. The Oak Hill native graduated from Marshall in 1995 with a bachelor's degree in criminal justice.
Morrison, who served as a graduate assistant coach at Marshall following his graduation, spent last season as the defensive coordinator and linebackers coach at Lehigh University. Under Morrison's guidance, the Lehigh defense led the Patriot League in scoring defense and fewest yards allowed per game. Lehigh also captured a share of its seventh Patriot League title in 2004, and the Mountain Hawks earned an at-large berth in the NCAA Division I-AA playoffs.
Prior to Lehigh, Morrison was the defensive coordinator at Southeast Missouri State University for three years under former Marshall assistant Tim Billings. During the 2003 season, Morrison's Indians led the Ohio Valley Conference in pass defense and ranked third in total defense. Southeast Missouri also ranked seventh nationally in turnovers caused.
Morrison has also coached at Hampden-Sydney and Sam Houston State.
Morrison and his wife Michelle, herself a Marshall graduate (B.A. 1993, M.A. 1995), have one daughter, Miya.
