My head would probably explode in disbelief though. I can guarantee that wont happen though. GSP would lose that exchange 10/10. He will probably strike some with Hendricks but it'll be that lunging jab game he likes to do these days and maybe some leg kicks. GSP wont stand toe to toe with Hendricks though. That would be like handing him the belt with a bow on it.
