Pernell Whitaker
Currently, Pernell Whitaker holds the longest unified lightweight championship reign in the history of boxing at 6 title defenses. From 1984 to 2001, he dominated the ring and is a four-weight world champion.
Deontay Wilder
Fans are eagerly waiting for the Deontay Wilder V Anthony Joshua fight as it is the fight who determines just which of the two is the world’s greatest boxer right now. As of 2015, Wilder has held the WBC heavyweight title, becoming the first American world heavyweight champion in nine years to do so – in fact, this is the longest period of time in boxing history that had no American heavyweight champion. Oh, his knockout-to-win ratio 98% and that’s something to boast about.
