What exactly happened between the negotiations between Ogawa vs Takada for PRIDE 17? I read Ogawa didn't want to do a legit shoot the same situation that happened with him and Inoki's new year show so things fell through.
As for Rickson vs Ogawa, I think people much rather see Rickson vs Sakuraba. Not to many MMA fans are big on Ogawa yet alone all the accusations of "works" with his fight.
