In US we don't defend that way. We play hard with lots contacts doesn't mean we foul or hand check every possession. Too many hand checking, tripping, pushing off, arm tangling, and so on. Playing hard and fouling are 2 different things. You wanna use proper contacts at your advantage when necessary. Not actively creating contacts while defending. You will be called and fouled out in no time. Or easily turn into a fight if it's on streets.
