I think it's a dick move by Cro Cop. I'm not saying anybody should fight for free. Mirko certainly isn't. I guess he doesn't have the confidence that he is gonna win the whole thing since he is worried about getting paid for the 2nd fight if he loses. I don't hear Wand, Barnett, or Nog bitching about getting paid for the 2nd fight if they lose. Probably because all 3 think they are gonna win the whole thing. I love watching Mirko fight, and if this does go through it will definitely suck.
I'm pretty sure that this is always how Pride has done it in their GP's. I'm sure Mirko knew about this before the tourney even started, so I don't understand why he would go all this way in the tourney to quit.
