Caballero vs Lopez would be a grerat fight ... I would pick Juanma but overall I would expect a great fight !!
The penalosa fight will be a measuring stick.... There are too many unanswered questions surrounding Lopez so it's hard to speculate... AS of now, sure he's been on a wreck and looks special but let's see how he deals with a real fighter before pitting him with someone else... Caballero is a battle tested fighter and Lopez isn't so for now, i would have to go with Caballero but i could be wrong... If lopez proves that he can take a punch, fight through pressure, and remain affective in the later rounds, then yea he can certainly beat Caballero, but right now, it's hard to gauge him.. Let's see how he deals Penalosa..
I think Penalosa would push Lopez to the limit ... he's a rugged veteran who knows all the tricks of the trade.
I'm a big fan of Caballero, and I think he would have a decent chance against Vasquez or Marquez, but Lopez destroys him.
Caballeros' too wild and gung-ho. If Lopez can keep his cool, as I'd expect him to do, he'll bang him out straight down the middle of those looping punches. Caballero has a good chin though, but JuanMa's power is awesome. I'd expect him to stop Caballero mid-rounds after an accumulation of damaging punchers.
