these greatest fighter debates divider people as much as politics. marciano was great in his day, but if i'm being honest, i think a prime hopkins as well as a slew of other fighters from middleweight to light-heavy would have their way with him. different eras, and as much as i hate to say it rocky was not much more than a 1-dimensional slugger who happened to be around at a time when the competition was almost laughable. he was very tough, and had great heart however!
