one of the more popular explanations why pride fighters done so bad in the ufc has been that theyre drugtested here unlike in japan, but wand has this to say:
“Actually, they do test in Japan. I was tested before and after my fights in Japan. But if you are thinking of Mirko (Cro Cop) and Shogun as examples, Mirko may have lost because he has so many other things going on in his life, such as his duty in government, and his business. Shogun went through a lot of changes before he fought in the UFC. He changed his home, he changed his training, and he changed fighting organizations. I don’t know why they lost their fights in the UFC; only Shogun and Mirko understand the reasons why they lost.”
