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.
If BJ Penn said GSP had to come down to 163 to fight him the internet would explode. And BJ would be called a coward.
BJ is a smaller lightweight than Georges is a welterweight.
