No way could Floyd stand a chance against fighters with the reach and size of Hagler and Hearns, Duran would have beaten Floyd too and Benitez.
I’m 100% Leonard goes 50-0 vs. Floyd’s. I think Floyd loses to Hagler for sure, Hearns twice, Duran at least once, possibly Benitez too. I’d say maybe he goes 35-5, 33-7 something like that.
Floyd didn't even really go 50-0 under his competition because he ducked several dangerous guys in his day...
With the emphasis on the “OH” I would say NO - and with defeats earlier in his career and depending on their severity/nature and overall greater wear/tear I believe it to be more likely that Floyd doesn’t achieve/pursue a record that comprises 50 fights anyway.
No. Duran beats him, as does Tommy Hearns. Hagler is full-fledged middleweight, so I doubt he would have even considered him. I think Mayweather is still a very talented fighter and would have beaten a lot throughout history though. I also think he does very well in the 1980s as a lightweight, but not as a welterweight. He would not have been able to move up and beat any of those I mentioned...
