Could the best version of Floyd Mayweather beat the Marvin Hagler who lost to Sugar Ray Leonard?

My view is a fact is a fact (an actual occurrence) and an opinion is an opinion ( An opinion is a judgment, viewpoint, or statement that is not conclusive, rather than facts, which are true statements.) and the fact is the official record demonstrates Ray Charles Leonard was the victor over Marvin Nathaniel Hagler in their bout which was held in Las Vegas, Nevada on April 6, 1987:

Official Judging
JoJo Guerra 110 - 118 Leonard
Lou Filippo 115 - 113 Hagler
Dave Moretti 113 - 115 Leonard

Now that I have taught you the difference between a fact and an opinion is there anything else you would like me to teach you? As a kind and empathetic person I would be more than happy to help.
