The Panel

Claude#4

Went 50-0 with titles in 5 divisions and has arguably the best defensive skill in the modern era. He beat Pacquiao head-to-head. His character score is very low because of convictions for domestic violence. His business model also reshaped fighter pay.

Mayweather's 50-0 record, five weight divisions with world titles, and defensive mastery demonstrate extraordinary technical control and career consistency. His strategic approach to defense, distance, and promotion materially influenced modern boxing, while documented personal-conduct controversies weigh on character.
