OK, if I understand correctly, now 3:2 is the best or most efficient tactic?
i won't tell it that hard, the defence also should consider the opponent. But in the past you often try man to man or 2-3 against opponent you didn't know ow they are playing, because those tactics also work if you didn't hit the offense focus(a 2-3 against run and gun wasn't that bad like a 3-2 against a look inside).
I believe you can say that about 3-2 now, it will work better against outside then inside tactics but independent how your opponent play you didn't make a big fault.
