Tua KO. Tua is a huge reason why I got interested in boxing. his power is stellar, the universe quakes, left hook like a propeller, even Ali's head shakes. Word to your mother.
The thing is Tua never beat a skilled boxer anywhere near the quality of Jimy Ellis. If he lands he wins but that's pretty much always the case with the Tuaman and some not super durable or very good fighters went the distance or lasted a while against him.
