Sakuraba.
I think Rickson didn't want any of Sakuraba.
I suppose his personal loss or whatever might have had impact in ONE fight falling through, but if he wanted to, he could have, and there were YEARS that they could have fought, and it most definitely didn't look like it was the money issue either.
My take on this is, if Rickson wanted this fight, he would have, outside that small window of time where he lost someone that his fans point to as a reason why he didn't. And there were many reasons, all the defeats, why Rickson would have wanted to fight Sakuraba, but he didn't.
I believe Rickson ducked Sakuraba, and I don't think Rickson would have been able to take Saku down and Rickson had no striking so.
Saku!
