If we use the best versions of each, then I think Gonzalez is pretty far out his depth. I think Zapata would whitewash him just like Ibarra did.
I haven't seen that one, the only Ibarra fight I've seen are the Herrera and Kim fights. Betulio was pretty far past his best for that one though, wasn't he? Or am I thinking of his fight with Herrera. Which ever one he lost on cuts, that's the one I'm thinking of. I was more thinking of Zapata's fight with Laciar, because I've always drawn lots of comparisons between him and Gonzalez. I scored that one for Zapata, barely. I think if Zapata can slightly beat Laciar, who I think is probably a little bit better than Gonzalez, he can beat Betulio as well. Although, Zap could get nailed and finished off. I think it's potentially an interesting fight, between one of the most complete flyweights ever, and one of the best defence fighters of all-time. Also, the name 'Tae Shik Kim' sounds like it's ripped straight out of Star Wars.
