Response to fstos, without wanting to sound rude, but how else do you think 'elite athleticism' happens?
DJ needs to work on his lateral quickness, and change of pace, and also become more comfortable playing PG. He is undersized to play as a SG at NCAA Div1 level, as I don't see him being able to guard bigger, stronger SGs.
His future lies in being to project himself to prospective programs as a PG. Is an under-rated ballhandler, however this isn't always apparent as is regularly played out of position.
