Generally, these are the training types you want to train to maximize training efficiency. If you are training a low potential player you can get away with other training types or if you need to play a player at a certain position. You just have to do a cost benefit analysis with your team and how important quick training is to you.
Pressure (OD) - PG
Passing (PA)- PG
Outside Shooting (JR) - SG
Inside Scoring (IS) - C
Inside Defense (ID)- C
Shotblocking (SB) - C
1v1 (HA/DR) - Two Position Depends on Your Player
Jump Shot (JS) - Two Position Depends on Your Player
Rebounding (RB) - PF/C
People generally don't train Ballhandling because HA is the devil and you get plenty of it from PA and 1v1 training. People do the Team Training (ST and FT) during short weeks like this week when you only have two games instead of three and all star break week, when they fire their trainer (because team training is not impacted by trainer level) or when their stud prospect gets hurt because its the only training that you can give to a injured player.
Hope this helps.
