So, Askren mentioned Khabib as the best wrestler in the UFC history, and I believe chael and Ben talked about hes pretty much a wrestler in disguise of Sambo. Obviously, no one took it seriously. I didnt. Then, I found this. On wiki. ...In 2001, his family moved to Machachkala, where he trained in wrestling at age 12, and judo from age 15. He began training in combat sambo again at 17 under his father... At 17. He started training combat Sambo at 17. He turned pro in MMA at age 19, a week from turning 20., and won Combat Sambo world championship at age 21. So, how legit would he be able to claim that he is really a sambo fighter, now I am not so sure.
