What im doing with my sf's is I got OD and trying to get passing out of the way first with ID, rebounding on 2 game weeks, and do js/1on1 when they're older since that is the easiest skill to train and you can start them at their natural position for it for js fowards training.
Don't get off track with him. 14 weeks of SB for 6 straight years would create a monster.
