Well hatton beats them both, as does judah imho... baldomir might have beaten them in his cinderella year
Hatton fought at WW twice. He got the weight wrong with Collazo and came in too heavy, but in fairness stylewise it was a bad matchup. Only the fact that Collazo isn't the biggest puncher got him through. Quintana isn't as clever as Collazo but punches harder..... he might have enough to get rid of the Hatton that fought Luis. The Hatton that fought Mayweather - i.e. doing the weight properly - probably does better against both.... but Collazo might not take the odd round off here and there, which cost him dearly.
I never said he should be included as a WW. But when he was one, none of these "top guys" wanted much to do with him. And if you're talking about the same Margarito who's promoter wrote a nice letter to Goosen saying "Don't contact me any more about a fight with Margarito" then you are sadly mistaken.
