In another category: perhaps the toughest lefty ever. I worked with Rolando Navarette once who could put you out for two weeks, and Limon beat him by absorbing his best shots, flush! Navarette was a bad dude in and out of the squared circle, very intimidating, like a little "Quasimodo" a mean guy who didn't know what the words hold back were.
Asking historians to rank fighters is a bit like asking a retarded kid (or REED) to divide 3674566 by 7
Gotta be top 3. I'd say Whitaker outranks Manny. I'd have Hagler above him too though you might conceivably make an argument. But I think he's certainly top 3. Flash Elorde & Tiger Flowers would probably be the next two with Vincent Salvidar, Khaosai Galaxy & Calzaghe behind them? Might well be an interesting project to make up a top 10 list.
Not exactly on topic but Manny is one of the few southpaws i've ever liked. If i had it my way they would be banned.
