There are tons of stars. When, one door closes another opens up. When it was early in the 2000's and DLH was the megastar nobody thought that Pacquiao would become a megastar. Time will tell, there will always be megastars there is no need to be concerned, and even by some strang reason there aren't any who cares? Boxing fans will always be Boxing fans. Just like in any other sport.
i say Saul Canelo Alvarez will become a big star, he is already adored by Mexico, he just needs to start fighting in the US, and he is soon, add to that he has some serious skill, a good personality and he is still young as hell so we will see. also andre ward, alfredo angulo, chad dawson, still have faith in victor ortiz, and even chavez jr.
The Cuban Trio of Gamboa, Lara, and Rigendeaux are gonna tear things up in the near future. Saul Alvarez from Mexico has the tools to be a BIG star, too.
boxers that fights like mayweather jr... all boxers should fights like him for boxing to be greater than MMA
