Sambo isn't even > wrestling in essentially the only country it is competed in, Russia.
Khabib washed out of freestyle when he was 15. Askren was the senior U.S. national champ, and went to the Olympics.
Khabib is from Makhachkala, essentially the wrestling capital of the world. I assure you, if he was that great of a grappler, he would have continued with wrestling.
That's not true at all. The reason Khabib went into MMA is because his dad owns and runs an MMA gym. lol
