by survive, you mean not get finished? because i can't see dariush or oliveira actually beating islam on the mat. i mean if davi ramos couldn't do shit to him from the bottom, charles oliveira sure as hell isn't going to.
i'd love to see the tony fight, but i think ferguson would get owned pretty badly.
i think chandler would be a really tough fight for him, he's a beast physically and he's a very solid wrestler himself. i think he could make it very interesting. but if islam drags him to the mat and keeps him there, then i agree, he's screwed. islam has that same wrestler / sambo style that isn't focused just on taking down and controlling guys, but also passing guard really well and finishing with submissions from the strong positions they get. it's beautiful to watch, really.
