It takes no balls whatsoever for Chael to take the fight on short notice because he has nothing to lose. He is coming up a weight class (although he has fought there before) and off a loss. He has done nothing to earn a shot and if he loses it would be easily dismissed since it was short notice, coming up a weight class, etc..
Jones is the one who would have everything to lose and almost nothing to gain from the fight. Thank god he turned it down. Dana is such an utter asshole, trying to turn this sport into a clown show. Making utterly retarded, nonsensical fights and then trying to blame Jackson or Jones when they rightfully laugh in his face for such idiocy.
ummm i think he was just trying to save the card cause there's millions of dollars already spent on the evenet
