No Floyd is a fantastic boxer, excellent resume and was a game changer for his era, but not necessarily in a good way. When discussing the best boxers of all time, his name will be mentioned in conversation but there are so many variables to take into consideration. There is an argument to have him in the top 10 of all time and there is also an argument to not even have him in the top 20 or even 30 of atg's. So many factors be considered. I'd argue he is the smartest boxer of all time though.
He is clearly in the argument along with Ali, Roberto Duran, SRR, Benny Leonard,SRL, Charley Burley et al
No. His record isn't impressive enough. He is one of the most skilled boxers in history, but there have been better.
