Just 'who' had the most controversial bouts.

Well, none other than Mr. Clay.

* Alonzo Johnson
* Doug Jones
* Henry Cooper I
* Sonny Liston I
* Sonny Liston II
* Ken Norton II
* Joe Frazier II
* Ron Lyle
* Ken Norton III
* Jimmy Young
* Earnie Shavers

Too much 'stinkeroo' there to put that man in the Top 7.

But yes, he was the 'best' showman and entertainer, for a period in time.
