The Importance of Having a Sambo Background

A lot of the guys who are having success at a Dagestan have Sambo backgrounds. I'm just saying that get into the highest highest levels, very rare for it to carry over. Satoshi Ishii won gold in the Beijing Olympics and literally got off the mat and gave an interview. He said, I want to go to MMA and I want to fight fatal. How crazy is that someone from another sport just doing that like at their peak moment?
