In high school, he had been a Detroit Free Press first-team All-State (Michigan) and second-team All-Midwest selection in football and an All-American in lacrosse.

[6] Morrison had been hailed as a blue chip athlete entering his senior season in the same pre-season summary.
[10] However, a poll of 14 experts selected Bettis first-team all-Midwest (Big Ten States of Illinois, Indiana, Iowa, Michigan, Minnesota, Ohio and Wisconsin because Penn State had not yet joined the conference), but only selected Morrison second-team all Midwest.
[11] In high school, Morrison was an All-American in lacrosse, along with Brother Rice and Michigan football teammate Gannon Dudlar.
[18] In his 1991 debut for Michigan against the Boston College Eagles, he opposed former Brother Rice teammate Pete Mitchell, who was appearing in his first game.

[29] At the time of his graduation, he ranked third in career tackles in school history, behind Anderson and Ron Simpkins.
[36] Although the Colts best records during his tenure was 9–7 in both 1995 and 1996,[37] the team made the playoffs twice and Morrison had a chance to play in an American Football Conference Championship game.
[42] He served as the defensive coordinator for his high school alma mater, Brother Rice Warriors, in 2000 and 2001.
[29] That same year, Scott Shafer assumed the defensive coordinator position at Western Michigan,[48] and Morrison served under him.
In addition to the team numbers he fostered Ameer Ismail, the nation's leader in quarterback sacks and tackles for a loss.

[54] Rice blew out Western Michigan by taking a 38–0 lead before allowing two late fourth quarter touchdowns for a 38–14 final score.
[55] On the eve of the Bowl game, the Broncos signed head coach Cubit to a five-year extension and there was no indication he intended to make any changes in his staff.
[56][57] Morrison's 2008 defense produced first-team All-MAC selection Louis Delmas, who appeared in the January 24, 2009 Senior Bowl and was the first safety chosen in the 2009 NFL draft.
[58] After a disappointing 2009 Western Michigan season in which WMU ranked 102 out of 120 Division I teams, Morrison was fired and replaced by former Hofstra coach Dave Cohen.
In January 2012, Steve Morrison joined the Syracuse Orangemen football team staff as the linebackers coach, reuniting with his former Western Michigan defensive coordinator, Scott Schafer, the defensive coordinator for the Syracuse Orangemen.
