If Marquez wins, is it the biggest victory ever by a Mexican fighter?

[Gandalf]

If he wins I think it should be regarded as a very, very significant win, perhaps the biggest win by a Mexican. Mayweather is unbeaten and Marquez is climbing two weight divisions to try and pull this off. The odds really are all against him and here he is his going for it with abandon.

Possibly yeah. No other Mexican has beaten anybody this highly ranked. I would say though that Barrera beat undefeated superstars at their best like Morales and Naseem whereas Marquez would be getting Floyd after a 2 year retirement. Long term it may hurt his legacy if people start saying it wasnt a prime Floyd and he came back for the wrong reasons.

Still a massive win.
