I know that Emile Griffith was knocked out by Ruben Hurricane carter in 1963 in round 1, but the only other fighter to stop him was Carlos Monzon in round 14 in 1971. But Emile was a good boxer in his prime, including wins against another smooth boxer, Nino Benvenuti. In his prime, I think that Griffith stands a good chance against Bernard The Executioner Hopkins. While Hopkins would be very unorthodox for Emile, but a very experienced pro like Griffith who has faced many would find his range to score a very close debatable decision over Bernard, no knockdown in this bout, but a lot of clinching, holding, and warnings from the referee to both.
A technical master piece between two chess players. Might not be a fight for the casual fan but for those who appreciate the technicalities Of the sweet science it would be a very interesting match.
