CHICAGO (AP) — For all he accomplished the past four years at Purdue, Zach Edey realizes there are some huge questions surrounding his game — almost as big as his 7-foot-4 frame. Though he was the national Player of the Year the past two seasons and led the Boilermakers to the championship game this year, he is viewed as a slow-footed defender who can't stretch the floor on offense, either. Those are two big marks against him as he prepares to enter the NBA.
