These teams are projecting where a guy will be, and even improved play next season probably won't help his draft position that much. He was drafted yesterday based on scouts projecting him to have above average power, a weak arm and decreasing foot speed (a forcast based on his body) that will regulate him to left. Yeah, showing to have more power would make him a more attractive left fielder to teams, but I'm not sure if a 5'8" guy can improve on an above average grade, and he's not going to develop an arm in one year.
