GSP wasn't complaining when BJ Penn was moving up to 170 to fight him. Even though GSP was much bigger than he was. This just goes to show me that GSP is not a warrior. I hate his fighting style because he is only cautious and can not finish anybody anymore. Hell even Chael has finished somebody recently.
BJ Penn issued the challenge. And BJ Penn made the adjustments necessary to follow through with his challenge. Now Silva is the challenger. And if he wants this fight so badly, he can do the same.
People love to act as though GSP picked on poor, little BJ, but BJ called out and went after GSP - not the other way around.
