By Anthony Mason: Due to his undefeated record, Mayweather is perceived as untouchable, and one of the best boxers of all time. That is false. Putting him in the top 50 would be extremely generous. He is undefeated, and although he is a good boxer, he is not undefeated because he is such a great boxer. He is undefeated because of the dearth of quality in his opposition. He is a all-time great businessman in the sport, but not when it comes to what happens inside the ring.
Although Mayweather has skills, his struggles against the likes of Maidana and Castillo, two solid but far from elite fighters, show that he is not the invincible boxer he is made out to be. To further prove what Maidana and Castillo did, it would be interesting to analyze which boxers in history would be able to beat Mayweather, and how. I decided to assemble a list of fighters from 126 all the way up to 160, all of whom would show that Mayweather is simply human.
