Has been dropped once in his fight with Gavril but that's mostly it, also he's been matched quite well with tough plodders so that he can polish his skills. He mostly wins by walking down and unloading combos, that tells me that he hasn't faced someone too good.
I remember the controversy but haven't rewatched the fight in ages , most of Benavidez's fights look the same and are entertaining on first watch but I almost never rewatch his fights with the intent of studying him cuz he doesn't do any subtle stuff at all at least as of right now , just plods and unloads with some occasional counters.
