Theory 1) I don't think they are making this match because they hate Sato. Dana is a huge fan of Sakuraba. I think they are giving Sato HGL on the chance that Sato will come out on top and have less fights before earning a title shot.
Less fights = less opportunities to lose.
They dont hate Sato.
Theory 2) They hate Sato and any Champion outside of the UFC. They had the intention of bringing Sato (A pancrase champion) into the UFC just to watch him lose 3 straight fights. Then, they will kick him out and point the finger at him and say 'see, the real champions are in UFC'.
You choose which theory you want, its definitely one or the other.
FEDOR, VOVCHANCHYN, MOUSASI, SAKURABA, GOMI, MINOWA.
