Morrison is the son of a basketball coach who coached at junior colleges in Montana and Casper, Wyoming while Adam was a young child. When he was in the fourth grade, the family moved to Spokane. He was first exposed to Gonzaga basketball in elementary school when he served as the team's ball boy. During his eighth-grade year, he lost 30 pounds (14 kg), and was at that time diagnosed with Type 1 diabetes. However, his illness did not keep him from becoming a star at Mead High School in Spokane. In his senior year, he broke single-season and career scoring records in his high school conference, and led Mead to the finals of the state tournament. Despite playing in the final game with hypoglycemia so severe that he nearly suffered seizures, he scored 37 points in a losing effort, Mead's only loss that season.

Despite his accomplishments, he was not heavily recruited out of high school, with Gonzaga being the only Division I school to strongly pursue him. Not surprisingly, he chose to stay near home for college.

He arrived at Gonzaga in 2003 and made an immediate impact, averaging 11.4 points per game in 2003-04 and being named to the West Coast Conference's All-Freshman first team. His sophomore year in 2004-05 was even more successful, as he averaged 19.0 ppg and made the All-WCC first team, as well as being named an honorable mention All-American.

Morrison began the 2005-06 season with a bang. In Gonzaga's first two games at the Maui Invitational, one of the most prestigious early-season tournaments in the sport, Morrison had huge scoring nights against two of the sport's top programs. In the first round, Morrison scored 25 points in a Zags win over Maryland. He followed up this performance with 43 points in a triple-overtime win over Michigan State in the semifinals. He matched that output against in-state rival Washington December 4, 2005 in a losing effort. However, Morrison and the Zags bounced back a week later, defeating Oklahoma State after he banked in a three-pointer with 2.5 seconds left to give Gonzaga a 2 point lead, and eventually the win.

So far this season (January 30, 2006), he has had nine games of 30-plus points, with four of them over 40. He is the leading scorer in men's Division I basketball, averaging 29.0 points per game. His scoring totals against teams in the so-called "major" conferences are no less impressive; he is averaging 28.3 points in 10 such games (with one left to play in the regular season, against Stanford).
