Clay was an entertainer as all boxers are , and as with all other boxers people like some and dislike others. I am sure if you posted a thread about Cotto for an example , lots will love him lots will respect him and some will dislike him.
I personally do not like Clay and don't think he was the Greatest boxer of all time , however it is evident some here disagree, so lets just finish by saying he was a boxer who entertained , love him or hate him.
