some crazy numbers there
Pudz earning as much as most UFC main eventers(probably equal to all his World strongest man comps combined purses)
I don't blame him for fighting,if he's pulling in that amount.
Yves Edwards 3k ??
Travis Lutter going from headlining a UFC main event,challenging Silva for his belt(oh yeah,the twat came in over weight,so non title fight )to getting 4k at this event,though to be fair judging on his performance 4k may have been a little to generous.
