The University of North Carolina’s College Sport Research Institute found that 11 of 95 Division I schools studied had at least 20 percent roster turnover for the 2009-10 season. The UNC study also excluded injured players as well as those who turned pro or graduated. Both studies include Kentucky, where seven players on Billy Gillespie’s final squad didn’t return once John Calipari took over in 2009 and brought his own recruits. Four of those former Wildcats have said publicly they were asked to leave the program.
