Canelo? Danny Garcia? Rigondeaux? One Time? Errol Spence? Broner? Mikey Garcia? Devon? Charlo? Andrade? I can't really pick one or 2 guys and say...yup that is the immediate future face of boxing. Rigondeaux and M.Garcia are too small to be the face of boxing. Typically it's WW and above. They are all pretty decent fighters.. but are any of them stars?
Be interesting to see if he fights Chavez, Ward or Sergio. Those are the only big fights available. He kills Quillin, but Ward's style may make GGG look bad. I would wager that Sergio never fights GGG. He would have a year or 2 ago but not now. GGG lacks the charisma to be a star IMO.
Canelo has the biggest fanbase and exposure from that list, even though he did lose last time to Mayweather. Rigo is too old and his own promoter seems on a bizarre vendetta against him. None of the last three on your list I reckon: M Garcia could be too small as mentioned. Personally I think Thurman has a big future, and Broner is building a name for himself and is already a three weight champion with possibly the most potential out of that list. Danny Garcia too could have a big future
The Charlo brothers, Danny Garcia, Leo Santa Cruz, Maidana, Broner, Crawford, Mikey G, Lucas is still in there, and One Time.
