Former UFC two-weight champion Daniel Cormier named his top five fighters in boxing and mixed martial arts history.
Daniel Cormier
This is my list, and I'm sticking to it. The greatest of all time: 1. Floyd Mayweather; 2. Khabib Nurmagomedov; 3. Muhammad Ali; 4. Georges St. Pierre; 5. Amanda Nunez. Muhammad Ali wasn't undefeated, I can't put him any higher.
Floyd Mayweather Jr's record currently stands at 50 wins, 0 loses and 0 draws. Of those 50 wins he has stopped 27 of his opponents, so his current knock-out ratio is 54%. He's boxed a total of 397 rounds, meaning his professional fights last 7.9 rounds on average.
