Focus on the elastics. For example in guards, training driving allows Jump Shoot to grow faster, with high Jump Shoot allows Outside Def to grow better. With bigs inside def helps rebounding which helps inside scoring. I personally have only trained big men so I know it works with bigs. Also If you looking to pick up any trainees let me know, I am the Assistant Manager/ Scout for South Africa’s U21 team and we are always looking for new manager to pick up players for the team.
