if you train two positions, train them one on one, as their JS and Handling needs some help in both cases, and their Driving would be helped too. Jump Shot training would help them, too.
If you train one position, switch between inside defense and inside shot, with slightly more focus on ID. Or train them in OD for one season at the PG-spot (have them defend as PF or C though); they both aren't too tall, so this won't be as painful as for some 7'-guy.
They need about 1-2 stamina trainings and quite some FTs, too, but focus on that during the offseason and the Allstar week.
