I vaguely remeber his fight with Alvarez, he was knocked down for the firtst time in his career and it looked like he was well on his way to his first defeat before it was stopped due to an accidental headbutt I beleive
Flawless fundamental skills, never held his hands below his chin, simialr style to JMM, in fact Nacho trained him too and for a little guy he packed some power
He destroyed Sorjaturong in 2 rounds during the time Sorjaturong was considered the next great champ, plus his fights with Alvarez (spelling) are one of my favs
He was great, I just dont recall him cleaning out any of the divisions, I could be wrong, that was a long time ago
