Ingame focus Defensive/offensive

Hello Guys

I got a noobie question regarding the ingame offensive/defensive focus you can set, is there somewhere i can read about them? I mean most makes sense, but i dont know all basket terms, for exsample "junk" what does that mean putting my focus on that? Also Two man on the offensive side?

Could nobody guide me to these ingame focus?

Junk defense means you have one or two defenders staying tight on their players (opposing stars for example) while the rest plays zone defense. Some examples are "box-and-1", "diamond-and-1", "triangle-and-2", ...
