I remember reading that Nick Fuller was young for his grade and may not be done growing. He is 6'7 now, so he could easily develop into a power forward if he grows an inch or 2.
Also, It's not like Miles hasn't been trying to get big men in this class....
Agau, zach hanson, Vitto Brown, Tory Miller, Alex Foster... etc.
Matthew Atewe and Aram Martin (Who are both 6'9) seem to be the 2 most likely players to finish this class unless Miles decides to try and get a juco/transfer.
