The K1 fighters have been in Ultimate style fights for a long time, K1 champ Sam Greco has fought NHB many times. Tua is faster then any Olympic wresler? lol. i too follow boxing and i dont know of any boxer in history who has been bigger, stronger, faster than Aleksandr Karelin, i would take Tuas left hook on the chin, and Jones’s right to the jaw over a little jab from Karelin any day. hasnt anybody seen Karelin before?
