I still remember very well Roberto "mano de piedra" Duran, together with Ray Sugar Leonard, Tommy Hearns, Pepino Lopez, etc. awesome fights where Sugar ended up being the best of all...in that period.
In Floyds "decade" there are not being really outstanding opponents to test Floyd to his limits. Floyd did beat Oscar de la Hoya, another great welter boxer, but he did it when Oscar was on his way down.
A couple of years ago Floyd gave a lesson to one of the few real strong opponentst: the Mexican unbeaten Canelo Alvarez. 13 years younger (I think) and unable to even come close enough to punch hard once Floyd in 12 rounds.
Manny is like Oscar de la Hoya was, in his way down, pitty, it would have been GREAT to see Floyd fighting either Manny or Oscar when there were at their best, especially Oscar!
Longing to see the fight even if is very early in the morning here : ))
