Dinosaurs were huge and powerful; they could not adapt and they died out. And so the big difference between dinosaurs and cockroaches is adaptability: one is able to adjust, while the other, apparently, couldn't... The same analogy applies to fighting, and probably any other sport. It's not always the strong that survive. It takes brains, guts, tolerance and forward thinking. We've seen this since the beginning of mixed martial arts.
