Lucious was dismissed from the Michigan State basketball program in January by Tom Izzo for displaying "conduct detrimental to the program." Although it wasn't clear if his dismissal was for only the rest of the season or for good, Lucious' mother said the next day that her son would be transferring. In the wake of that news he set up visits with Iowa State and Marquette, and now he is set to become a Cyclone.
Already at Iowa State, as mentioned, is Chris Allen. He was kicked off the Michigan State basketball team last summer and transferred to ISU. He will be eligible to play next season, during which time Lucious will take a redshirt year.
Another connection Lucious has to Iowa State is that Diante Garrett is there. Garrett, like Lucious, is from Milwaukee, Wisconsin. Garrett is a senior, so he won't be around when Lucious joins the program next season. I'd imagine Lucious heard from both Garrett and Allen while he made his decision, though.
