Re: What would it mean if Robert Guerrero beat Mayweather?
bad for boxing. Guerrero is a decent fighter who does nothing exceptionally well and who relies on dirty tactics a lot (as does Ward). It would be a turning to the paradigm of "dirty" trumps "skill" with which Hopkins was always flirting. Cementing the coffin on the legacy of well rounded fighters who came up the hard way (as Floyd did at 130 - challenging himself very early in his career against great and good fighters from Manfredy to Genaro Hernandez to Corrales to Castillo)
I think Floyd is one of the youngest "complete" fighters to come along - all these up and comers show glaring flaws in their early fights that really indicate they aren't world class. Those kinds of things don't happen when you watch the entire early careers of say Barrera or Marquez or Hopkins (who was a murderer early in his career). The only ATG who looked like garbage early was Pac, and he fixed that somehow.
