Depends on whether you want to make him a PG, SG, outside SF or Combo G.
for a PG, train OD and Passing alternatingly during next season, and proceed training JS and JR afterwards. You don't want to train Driving as much as in other cases as his IS is pretty weak.
for a SG, train OD and JR alternatingly during next season, and proceed training JS and some Driving afterwards. Some IS could be beneficial, if it doesn't pop with the Driving and JS training. Passing is not as important there, but could need some training up to proficient or so.
for a Combo guard, train OD, JR and Passing alternatingly for two seasons before focusing on JS and Driving.
for a SF, you want to improve his inside game as long as he is young, so spend his next season training IS and some ID. Proceed training Driving and JS later, with some OD training in between.
Generally speaking, his Stamina should be trained up to mediocre at least, and similarly FTs up to strong. This can happen during AllStar Weeks and Playoffs, though.
