Word has been going around that Brock got about $3 million. I think he got 4% of PPV money. It was in the LA Times a couple days after the fights.
According to this interview... http://www.bloodyelbow.com/2009/7/17/953169/phil-nurse-and-john-danaher-talk ...GSP was so upset with himself for not finishing the fight he insisted on combing over the fight with his trainers for half an hour afterwards and insisted that they show him the mistakes he made, delaying the press conference. Something like Anderson Silva going a few more rounds after the Cote fight. This is the dedication required to be the best.
he almost had him at the end of the 3rd and if he hadn't of torn his hammy, he may have been able to be more aggressive in the 4th and ended it... like I predicted
