To hard to train with other players in mind.
If I have a small forward that has a strong ID rating, and a small forward that has a strong OD rating, I can then focus on training other aspect for them such as driving, shooting, etc.
I find that having a small forward with strong inside defence and rebounding, and a small forward with stronger outside defence and handling/passing, I can train a skill that suits them and the other guards like shooting or outside scoring, give them both 48 minutes over the week and they both become better players.
I generally train guard type skills including outside shooting, handling and passing, and buy my big men. I find this is working better for me.
I suppose it comes from ABBL where defence is king, in ABBL all they talk about is defence, some more defence, and then for a change....defence.
