Greg Gibson actually won a world title in sombo in 1981 or 1982. He was the 1st and I believ only American to do so. He was also a world/Olympic medalist in Greco and freestyle and a NCAA D I All American. Talk about a versatile wrestler. The interview I am referring to I got here http://www.onthemat.com/node/1011898But sadly its so old the link is now inactive.
