I think a younger DLH wins at welter, possibly even by stoppage. However, it's not a fight that should really be considered, Mayweather should still be a lightweight really. DLH's a noticeably bigger man.
First of all , the closeness of their fight was pure hallucination by the judges. Mayweather won as he pleased. Floyd was penalized by the judges because he was doing just enough to win. Floyd apparently didn't want to waste energy. Also, what is this myth that at 147, De Lah Hoya was a great fighter, a beast? He probably should have lost the decision to Whittaker, just barely beat Quartey, who should never be confused with a great fighter, and jogged away victory in what should have been his signature fight.Great fighters do not run in the biggest fight of their lives. Mayweather, on the other hand , has done everything he had to do, and even when Castillo fought him close, Floyd dominated the rematch. Floyd would beat DLH to the punch no matter what weight class.
Floyd would have way to much for Oscar at any point in his career!!!!! He's on another level to Oscar
ODLH has the size/strength advantage... but PBF has speed and he's a *****n smart fighter. so it would be crazy to say that it will be rd1KO for oscar... probably 60%-40% ODLH
Oscar ALWAYS had stanima problems. Where have you been? He admitted the reason he RAN from Tito was because "I was tired" He gassed against Shane in the first fight as well.
