" not all suplexes will cause the person to land on their heads and that shoulders will help pad the fall. But every time I see the Khabilov-Pichel finish, I cringe a little bit because he falls squarely on his neck without his hands to brace the fall "

Severn never used the suplex in The UFC again. Was it politics? Did they tell him not to do that anymore? Why else would he quit using it? That's, as he said: "The heart of Greco Roman wrestling." I don't think he'd just remove "the heart of Greco Roman wrestling" from his arsenal unless he was told he had to. Maybe they thought it would result in a death eventually and that was the last thing that The UFC needed at that point in time when it was already under so much scrutiny from politicians and the mainstream media calling it "human cockfights."
