Hernandez is a pretty standard Mexican brawler who can box a little but doesn't have much natural talent. I don't think I've seen much of Beltran, but he should be the favorite. Could be an exciting fight though.
I have seen Miguel Beltran jr in about 7 fights, he is one of my top contenders, not a lot of people knew him before the mexican version of the contender, he won it, still undefeated, he boxes really well...
I had hopes for joksan until he began brawling. He has decent skills but lacks power somewhat like Luevano. Beltran should edge this one out.
