I think you misunderstood. Pernell and Chavez would have murdered DLH if they were young when they fought DLH. Maybe on Micro level Floyd outclassed DLH. But on a macro level, he did not. It was a split decision draw and many including Floyd's own family members thought Oscar won the fight.
Perhaps I misunderstood. Sweet Pea definitely should have got the decision over Oscar IMO even when they did fight. I thought Floyd beat him quite handily as well and I love Oscar and don't like Floyd.
It's fine. I think the sentiment is that Floyd beat DLH, but he did not put on an outclassing of Oscar and that it wouldn't be a total robbery to have Oscar winning 6 rounds.
I thought Oscar lost all of those rather convincingly too, and although the Sweet Pea one was probably the most debatable of that lot, I definitely believed Whitaker deserved to be victorious in that one. Incidentally, I had Oscar beating Quartey, and also strongly believe he bested Trinidad.
Mosley is a top 10 lightweight of all time in Ring Magazine rankings earlier in 2000's He had trouble with boxers so I'd bet prime Mayweather beats him at any weight although lightweight Mosley stands best chance. Shane is a Hall of Famer but not top 50.
