boxers and MMA fighters

[Glenn]

FWIW, the IBA is not considered a real title. Also, Super Heavyweight is not a generally recognized division. The title fights were 4 rounders, while any recognized title fight is scheduled for 12 rounds. Larry Holmes was 52, and beat him handily. Against any real boxer he would be either KTFO or the fight would be stopped due to accumulation. The 130 lb version of Mayweather would UD butterbean 120-108 on all cards.
