This is strange - If you train SF/C in a skill lke rebounding and a player has played 24 min. as C+24 min. as SF he will NOT get full pot of training? This is pure math isn't it?
You can't train only SF/C.
If you're training PF/C, and the player plays 24 minutes at PF, and 24 at C, he gets full training.
If you're training PF/C, and he gets 24 minutes at SF and 24 at C, he gets 24 minutes worth of training.
