Floyd Mayweather is arguably the greatest boxer of all time. The legendary fighter retired with an unbeaten 50-0 record while amassing an emphatic resume of world title fights against many high profile names.
The boxer faced and defeated the likes of Canelo Alvarez, Oscar De La Hoya and Arturo Gatti.
However, after becoming a world champion, he rarely competed in fights that were not for world titles. His clash against UFC star Conor McGregor was mostly for entertainment, bragging rights and of course, money.
In 1998, 'Pretty Boy' starred in his first world title fight after two years of being a professional. The matchup was against Genaro Hernández in the super-featherweight division, and it was Mayweather's eighteenth pro contest.

'Money' went on to have seven non-title fights for the remainder of his career and he, of course, won them all. Juan Manuel Marquez is also on this list. In 2009, Mayweather beat the Mexican via unanimous decision.
Ultimately, the unbeaten fighter had a perfect career even while facing the very best fighters of different eras in championship bouts. The American's professional career ran from 1996 to 2017 and included three retirements.
