He ruined Antwun Echols alright because Kid Dynamite was shooting hard with both hands at the start and had him down with a shot on the break... Later on, he was telling his second that he couldn't go on because he was so tired - also picked up Hopkins and slammed him to the floor in the second fight. Robert Allen threw himself down three times in round four, two low blows and a punch after the bell in the rematch - he clearly didn't want to fight anymore and was stopped in the seventh. Tarver fought the smaller man rough game when he was predicting a 5th round KO. There are many other examples, Hopkins is really terrible.
