I've only seen a couple of his fights on youtube, that sounds like a tough training routine.Marquez got hit alot by Juan Diaz in the first half of their fight, and he got hurt once. Diaz is known as good pressure fighter who lacks power, and i hear that Valero has awesome power so maybe if it had been him fighting JMM that night he would have done better? Impossible to say since he's never fought a big name , but the way people talk about him Valero must be superhuman or something.
