Rose announced in late June that he was moving closer to home to be near his mother, who is suffering from lupus. San Diego State was also involved for Rose when he left Baylor.
"We are really excited that L.J. is joining our program," Houston head coach James Dickey said at the time. "He is a skilled guard who passes the ball extremely well, can score and is a very unselfish player with great leadership qualities. L.J. has great familiarity with our program and our players, and we look forward to having him as a part of our team."
Rose, a 6-foot-4 point guard, was a four-star prospect coming out of high school but didn't see consistent minutes during his one season in Waco. He averaged 0.9 points and 1.2 assists – but did have 14 points and 12 assists against Division-III Hardin-Simmons.
Earlier this month, Gary Parrish wrote about the addition of Danrad “Chicken” Knowles, who was ruled ineligible last season but will make an impact this year in the Cougars' frontcourt. Rose and Knowles will combine with the inside-outside combination of Danuel House (12.4 ppg, 4.9 rpg) and TaShawn Thomas (16.9 ppg, 9.8 rpg) to form a quality quartet for Dickey as Houston enters the American Athletic Conference.
