There is money on the line. World Champion Guilherme Marchi has accepted the challenge of PBR Director Tom Teague that no one can ride his 2008 World Champion Bull - Bones. Teague is so confident that he's put up $20,000 of his own cold hard cash for the challenge. The clash of champions (as I am now going to call it) will be featured on Saturday (4:30pm Eastern) on NBC during the regular broadcast. My prediction is that Marchi will buck off early, about the 3-second mark. Bones doesn't fit Marchi's riding style BUT if anyone is to conquer this bull, it would be the reigning champ. What do you think will happen? Leave a comment below.
