If I were you, I might sell Goff, since his HA is only at pitiful. Plus, his IS/ID is a pain in the butt. If you decide to keep him, I would make him the 3rd trainee.
This week is only a 2-game week, and they are all draftees, so unfortunately, the most effective training for multiple players would be to play one guy at PG and another at SG for 48 minutes in your scrimmage on Thursday. You can decide if you want to train 1v1 Guards or Jump Shot for Guards.
Training Plan
Train OD until they are all at 8 or 9
Train 1v1 Guards to raise HA/DR to 7 or 8
Train PA until they pop to 8
These are basic goals I am suggesting, and you can specify them to your liking. Good luck training them.
