Granger averaged a career-best 19.5 points per game and also led the Lobos in rebounding (9.0 rpg), steals (1.32 spg) and blocks (1.41 bpg) as a junior in 2003–04. He became the first Lobos player to lead the team in all those categories in the same season and was awarded the Bob King Team MVP Award. He also became just the second Lobo in 33 years, and the fifth all-time, to average more than 19 points and nine rebounds for an entire season, joining Luc Longley, Willie Long, Mel Daniels and Ira Harge. A First Team All-Mountain West Conference selection, Granger was twice named the league's Player of the Week for the weeks ending December 22 and January 25.
