Guice was a high-scoring guard on Butler's basketball teams in the early 1990s, and he helped engineer a turnaround in the Bulldogs' basketball fortunes. He helped lead the Bulldogs to an 18-11 campaign in 1990-1991, Butler's first winning season in six years, and then sparked a 21-10 record the following season, just the third 20-win season in Butler basketball history. A two-time Butler MVP and two-time All-Midwestern Collegiate Conference performer, Guice finished his career in sixth place (he currently stands eight) on Butler's all-time scoring list with 1,607 career points. He led Butler in scoring in each of his final two seasons. The 6-4 guard still ranks 10th on Butler's all-time list for three-point field goals (174).
