things like the speed option much in the NFL. The opposing athletes are too big, athletic, and talented for it to work. If NBA teams defended the way Houston did today, they'd get dunked on every possession. If you want to see examples of NBA teams defending that way successfully, watch a jazz game. The jazz' ball handlers suck so teams defend them aggressively and the jazz turn it over a lot. Against a team with a good ball handler, that approach is a terrible idea for an entire game.
