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.
Not sure why he would care if Penn came up. The whole thing here is come to 170 if you want to fight GSP.
