I suppose he had his inner line better then the opponents and alongside the GDP he was confortable enough to focus to pressure his outside line, which isnt stupid, if he has a good outside line with high outside defence. I think tbat high OD actually helps against inside tactics, because the opponent cant transfer the ball under the basket, which is showing usually in high ball losess. Didnt do lots of experimenting, but i usually practice 3-2 defence and it works well for now.
