Two fighters who never shone too bright in an era full of golds. 12 round who gets it? Best version of both.
This is a problem with judging (relatively) contemporary fighters. Fighters today do not fight as much, and, to boot, feast on a diluted pool of fighters when they do fight (because fewer fighters plus the proliferation of weight classes and belt organizations). So you've got a fighter who has some 20-odd fights against munchkins mostly and still requires a few gifts at home to compile an "unbeaten" record. Yet, everyone goes gaga at the "0" (with special emphasis on the quotation mark, because it is not really true) on the loss column and pits him among all-time greats. (Yes, it's been a while since I saw them, but I thought the Thai clearly deserved to lose at least two of the fights I watched; one I even think most reasonable Western referees would've stopped him from continuing.) Mind you, I don't think Oguma is an all-time great. But he held his own against all-time great talents. Sitbangprachan has to do a lot more than knock out Blanco (who's not even among the best of Myung-woo Yuh's wins - and Yuh didn't exactly face a murderer's row of opponents to begin with, to put it charitably) to make me think he belongs in the same ring with even the very pedestrian Oguma.
