In a surprising but welcomed move, the NCAA announced in January significant changes to its rules regarding collegiate underclassmen's ability to test the waters of the NBA draft. It's necessary to note that these are NCAA rules, not NBA ones, which is important because the organizations conflict in one key area that might give some freshmen pause this April before electing to throw their names in for the June 23 draft. From 2009-15, any collegiate underclassman who made himself eligible for the NBA draft and appeared on the NBA's official early-entry list lost his college eligibility.
