They say that Tua is the hardest puncher in boxing. He knocked out John Ruiz, the current WBC Champion in 19 seconds. He may be the only heavyweight ever to knock out 2 champions in 30 seconds or less. I seriously doubt the fight was staged. But I agree with whoever said they don't think he can be the champion. He might win a championship with a knockout, but I don't think he could keep it for long. He is slow and many fighters could outpoint him. He is one tough S.O.B. though.
