Marvin Bagley III committed to Duke as a class of 2017 recruit last month, but he still needed approval from the NCAA to be able to play immediately. The 18-year-old received it on Friday. Duke basketball announced on Twitter that its top recruit has been given the green light. Bagley averaged 24.6 points and 10.1 points per game as a senior at Sierra Canyon High School in Chatsworth (Calif.) after sitting out his junior year due to transfer rules.
