Re: Myung-Woo Yuh vs De-Jesus I: Utterly one-sided.
Haven't watched it in a while, but with DeJesus at least, I don't think it was really the height or reach that bothered him, as much as it was DeJesus' movement and refusal to engage on Yuh's terms. I think he pretty much made a stinker out of it in the rematch, and brought Yuh somewhat down to his level.
With Olivo (again haven't seen it in a while), height and reach might have been an issue. But I don't think Yuh was ever really comfortable with competent boxer types.
