Passing trains also DR and HA, but much slower than 1 on 1. I wouldn't rely on passing to train HA and DR. I know what kind of player you are trying to create from another thread, so I would suggest rotating training of Passing and 1 on 1 as someone already suggested here. Whenever you can, train 1 on 1 for SF/PF position so you get a few skillups in Inside shot as well and you will create a monster PG for inside tactics.
