Here's the relatively young fighters I think can/will become stars and I LOVE:

Miguel Cotto
Jorge Linares
Edwin Valero(those 3 I've followed from day1 and it's been amazing to see them develop)

Then these guys are just awesome to watch and could be stars in their own right:

Kelly Pavlik
Steven Luevano
Cristian Mijares
Abner Mares
Juan Diaz
Juanma
Takefumi Sakata(his style will always lead to exciting fights)
Bad Chad Dawson(HUGE PROPS TO CUtmeMick,he called it on this guy before anyone else,most,myself included,had not even heard from him until Mick brought it up)

There are a few others but those are the ones that stand out imo. In fact if you look at that list,alot of those fighters are latino,and are going to step up in place of aging warriors like Mab,EM,Arce etc/
